She's still rocking hair the color of Smurfette's skin, but it doesn't look like newly single Katy Perry is singing the blues!

Last night the pop star co-hosted the GiveLove charity event with J. Molinari Jewelry designers Markus Molinari and Jason Arasheben at the grand opening of 1 OAK Las Vegas at The Mirage, and she looked absolutely amazing on the red carpet. The "The One That Got Away" singer been laying low since the news broke in late December that she was splitting from husband Russell Brand, so it's good to see her back out and about.

Katy and Marcus presented a check for $50,000 to GiveLove's co-founders, Patricia Arquette and Rosetta Getty, and other guests at the bash included Paris and Nicky Hilton, Scott Disick, Chris Evans, David Arquette, Christina Milian and Shenae Grimes. Sounds like a blast!

In just a year's time, the couple went from confessing their love for each other on Twitter, to Katy Perry completely unfollowing her soon-to-be ex-hubby, aka RustyRockets, on the social media site.

How very passive aggressive of her!

Brand, who filed for divorce from Katy last month, is still following his ex on Twitter page, but his last Tweet was Jan. 5 so he may not have gotten around to removing her just yet.

The Arthur star said in a statement after the divorce that he knows they'll "remain friends," but unfortunately, their Twitter relationship has officially come to an end.

"She's limiting those interactions. He's being so atrocious that she feels like she never really knew him," a source tells US Weekly. "Katy is insulted and feels betrayed that Russell has treated her so poorly. She will never forgive him. Ever."

Making her first appearance since announcing her split with Russell Brand last month,
Katy Perry took to the stage on Thursday night to perform her second to last concert for the 124-date "California Dreams" tour, at the Sentul International Convention Centre in Jakarta, Indonesia.

The "Teenage Dreams" singer has been Tweeting her excitement for the second to last show, writing, "I'm SO EXCITED to FINALLY be in INDONESIA! U guys have waited forever #timetodeliver." A few hours before taking the stage, Perry again Tweeted, "It's the day of the show y'all! Can't WAIT! #JAKARTADREAMS."

The only sign that things have changed in Katy's life came when the singer removed footage of her wedding to Brand from the concert, which was originally meant to play during the track "Not Like The Movies." Perry replaced the video with random cartoon images instead.

The performance comes just one week after a blue-haired Katy was spotted shooting an Adidas commercial in LA. She is set to perform her final show on Monday in Manila, Philippines.

Sims

Katy Perry is sexy in real life and in the virtual world!

Russell Brand's soon-to-be-ex has been made into a video game character in "The Sims 3 Showtime."

The 27-year-old songstress said the following about her new gaming gig:

"I love how you're able to play out different stories through your Sims characters - giving them different careers and watching them succeed. It's cool to see the Sims' stage performances in The Sims 3 Showtime decked out just like my California Dreams Tour - even my cotton candy video screens are in there! I always like to think of myself as a cartoon, and now I'm a Sim!"

A collector's edition version of the game will go on sale in March.

Though it was previously reported that Russell Brand was moving out of the $6.5 million Hollywood Hills home he shares with soon-to-be ex-wife Katy Perry, it seems as though she's actually the one packing up her belongings!

Today X17 photographers snapped pictures of moving trucks at the couple's former residence, but get this -- when they arrived at a new pad three miles away, Katy's assistant, who was driving her black Audi, was also there!

It seem's Katy's snatched up a $1.9 million pad at the end of a quiet Hollywood Hills cul-de-sac. It's a 5-bedroom, 5-bath home with great views, but certainly a down-size move from the retro Los Feliz home she was sharing with Russell. Seems like temporary digs for this superstar, until KatyCat finds something a little more glam!

There will be no awkward run-ins for recent exes Katy Perry and Russell Brand at the People's Choice Awards this Wednesday!

The "Teenage Dream" singer, who is up for seven nominations this year, suddenly pulled out of the January 11 awards show on Monday, confessing via Twitter:

"Unfortunately I will not be able to attend the People's Choice Awards. I want to thank u all for voting for me, fingers crossed! #KATYCATS."

Perry originally confirmed that she would attend the 28th annual PCAs a few days prior, but then abruptly changed her mind on Monday.

The singer broke her silence on her divorce over Twitter just one day earlier, expressing, "I am so grateful for all the love and support I've had from people around the world. You guys have made my heart happy again."

Brand, who filed for divorce from Perry on Dec. 30, after just 14 months of marriage, was also invited to the awards show, but he reportedly declined to go "a long time ago."

It's been a difficult 2012 so far for Katy Perry!

She started off the new year with news that hubby Russell Brand had filed for divorce and ever since, she's been in hiding.

But the singer is starting to emerge ... she Tweeted to fans Saturday:

"I am so grateful for all the love and support I've had from people around the world. You guys have made my heart happy again."

Brand, 36, cited "irreconcilable difference" in his divorce filing from his wife of only 14 months. Perry, 27, was on vacation in Hawaii, while Russell spent the holidays in his hometown of London.

The web was abuzz with speculation the couple would soon announce a split and it finally came Dec 30.

And Katy has now firmly and definitively addressed the subsequent speculation and the reason's for the couple's divorce, Tweeting Saturday night:

"Concerning the gossip, I want to be clear that NO ONE speaks for me. Not a blog, magazine, "close sources" or my family."

Katy is distancing herself after reports her parents mentioned their famous daughter in church last week. The evangelical ministers at Churck on the Rise in Westlake, Ohio told their congregation: "I'm sure Katy is trending on the Internet just to get you to church tonight. I mean all over the world, who knows how God is bringing them in? The most important thing is you are here and God wants to put the fire in you in 2012."

We'll wait to hear the real story from Katy ... if she ever decides to tell it!

Following reports that Russell Brand mocked Katy Perry's family and their religious beliefs, her parents, Keith and Mary Hudson, have spoken out about her split from the British comedian.

The Hudsons, who are Christian pastors, recently spoke to their Church on the Rise congregation in Westlake, Ohio for the first time since it was announced that Katy and Russell were calling it quits. "I'm sure Katy is trending on the internet just to get you to church tonight," Mary joked. "I mean all over the world, who knows how God is bringing them in? The most important thing is you are here and God wants to put the fire in you in 2012."

Keith told the crowd, "I love my daughter and I will always love her. Stop being judgmental and critical. Do not close the doors to your loved ones, especially your children. Just because they do not like what you do or what you are, they are still praying that you stay in the race. They are counting on you. I believe in God, for every one of my children."

As far as Russell ridiculing Katy's parents, a source told The Sun, "Russ was forever making lewd jokes at the dinner table and poking fun at her parents' beliefs. He managed to restrain himself in the beginning, [but] as the marriage progressed, he got worse and kept winding up her family."
