Katy Perry attended the 2013 Costume Institute Gala on Monday night, and while she looked pretty, the gold crown and embellished Dolce & Gabbana dress aren't in any way punk, so we're kinda disappointed. Maybe we need to look deeper?

"Tonight for The Met I am channeling the OG queen of PUNK, JOAN of ARC," Katy tweeted, and she also posted a shot of her jewel-adorned nails:

At least she matched!

We would rather catch one of her concerts than a play!

Katy Perry got all dolled up to catch a performance of Kinky Boots on Broadway today, and the sexy singer clearly isn't staying in bed with a pint of Ben & Jerrys following her split with John Mayer!

Just last night, the "Fireworks" crooner took in the Daughters concert at the Bowery Ballroom, and she was rubbing elbows with the one and only Rob Pattinson! Although R-Patz is still with K-Stew, we can't help but dream of these two coupling up!

Being her beau isn't all that easy, though!

Hard at work on her upcoming album, the Grammy winner admits that her new tunes will be a big departure from the upbeat pop tracks on Dream, and that the lyrics will reflect the heartache of her divorce from Russell Brand and the sadness of her split with Mr. Mayer.

"It will be a much darker album than the previous one. It was inevitable, after what I went through. If I had a time machine and could go back in time, I would. But I can't, so you'll discover another part of me," she recently revealed at an ASCAP event.

So will she pull a Taylor Swift and do some boyfriend bashing?

"Maybe I'm not specific with names, but that's my lockbox where all my secrets go. Writing is like therapy. [My songs] stem from the truth inside me. I just want to be relatable, and to be adopted as some else's soundtrack," she added.

We can't wait to hear her musings!

Kate Holt/UNICEF

Fresh from her split with John Mayer, Katy Perry has traveled to Madagascar with UNICEF, where she spent time with abused and abandoned children and young mothers at a local protection center.

This is her first visit as an ambassador for UNICEF, and she helped raise awareness for programs focusing on health, nutrition, child protection, and youth development.

Perry said in a statement:

"In less than one week here in Madagascar, I went from crowded city slums to the most remote villages, and my eyes were widely opened by the incredible need for a healthy life - nutrition, sanitation, and protection against rape and abuse - which UNICEF are stepping in to help provide. I am grateful to UNICEF for giving me the opportunity to see first-hand how their programs make a real difference in children's lives. Support for UNICEF is saving children, I am a witness to it."

Katy and John after dinner on Valentine's Day

Katy Perry and John Mayer have split for the second time, according to Us Weekly.

Though multiple sources confirm that the two have broken up, one insider tells the mag, "It's not over until it's over. You have to see how things play out." Another added, "She's leaving the window open. They have both been so focused on work."

Katy and John started dating in June of 2012, but they ended their romance in late August, only to reconcile and get back together in September. In November they went on a romantic vacation to her hometown of Santa Barbara, and they seemed fine on Valentine's Day (see pic above).

Things seemed fine earlier this month too, as Katy tweeted on March 2, "My boyfriend is taking me to a kitten shelter in his truck. I can't think of a more perfect Saturday."

However, on March 10, she wrote, "Chiropractor, Therapist, a hike, and a psychic reading. Come on Monday, give me your best shot," and two days ago she added, "ATTENTION: Mercury is OUT of retrograde today. Thank GOD." Wonder why things went wrong ... and so quickly?

Looks like Katy Perry and beau John Mayer may be tying the knot soon. Check out her ruby red ring ON her ring finger!

The sexy crooner reportedly popped the question to the "Fireworks" singer last night while the two enjoyed a sexy Valentine's Day dinner date at Vincenti in Brentwood.

Katy was all smiles while leaving the restaurant with her man, and of course, she couldn't help but show off her shiny sparkler!

The night before, Mayer and his ladylove hit up Katsuya in Brentwood for a sushi date. Wow ... these two have been inseparable!

Wonder what Perry's ex Russell Brand thinks about her settling down with Mayer?

You can't blame her for being concerned!

Katy Perry "doesn't approve" of her pal Rihanna's decision to reunite with Chris Brown, and their once tight bond has suffered because of it, sources tell Us Weekly.

The "Fireworks" singer and the "Stay" crooner have been close for years, but the two apparently went out of their way to avoid each other at the Grammys last Sunday.

"They aren't tight anymore because Katy doesn't approve of Rihanna dating Chris Brown," the source adds.

The brunette bombshell chose to stick by her man John Mayer all night at the award show, while the Barbadian beauty put her love for Chris Brown on full display with some very public PDA!

It's so sad their friendship is struggling, but we're going to have to agree with Katy on this one!

For Katy Perry and beau John Mayer, love is definitely in the air!

The sexy twosome hit up Katsuya in Brentwood for a sushi dinner date ... and left hand in hand with big smiles. Looks like the Valentine's Day spirit has come a little early.

We couldn't help but ask Mr. Mayer if he's popping the question on V-Day! Check out his reaction.

After getting a look at Katy Perry's flawless figure, we're green with envy!

Katy posed for photos on the red carpet at the 2013 Grammy Awards on Sunday at the Staples Center, and she turned heads in a sexy green Gucci dress. Beau John Mayer was at the show, but interestingly enough, Katy brought Girls hottie Allison Williams as her plus one!

“She’s the hottest date,” Allison gushed to Anderson Cooper the other day. “She’s a friend of mine and she’s nominated, as she should be. I can’t wait to go. Obviously she’s awesome. She’s the best.”

Katy was nominated for Best Pop Solo Performance for “Wide Awake," but she lost out to Adele.
