The Hiltons are definitely enjoying their family vacation in Aspen, Colorado.

Nicky and her mom Kathy ditched the slopes for the day and bundled up for an afternoon shopping trip. No wonder the Hilton girls are hot ... look at their stunning mom!

Paris has been focusing less time on shopping and more on skiing. The heiress recently Tweeted:

"Love skiing down the mountain blasting @DJAfrojack @DavidGuetta & @Kaskade on my Ipod. It's like clubbing in the snow;) #RavingOnTheSlopes."

Nothing like spending Christmas in the snow. Life is good for the Hiltons!

Paris Hilton's parents, Rick and Kathy, turned up at the LA Superior Courthouse today to support their friends, the Jackson family, at the manslaughter trial of Dr. Conrad Murray.

Kathy went to high school with Michael and the families have been friends ever since.

Today is set to be the last day of testimony, so Kathy wanted to lend her emotional support. Janet Jackson made an appearance today as well, glammed up in an off-white pantsuit with black accents.

Last night Kathy Hilton dined at BOA in West Hollywood, and she was super sweet to photogs as she waited at the valet for her car. Kathy recently did an interview with Paris to promote her new Oxygen show The World According To Paris, and mama Hilton reveals that she's learned a thing or two from her daughter!

"I’ve learned that all of us in life go through the bumps in the road as I’ve mentioned before and that you are persistent and you keep on keep on keeping on and you learn from those mistakes," she says. "I appreciate that and I like that she would pick herself up by the bootstraps and say, 'I want to make this better,' or 'I want to move forward.' I love that. I think that’s what I most admire."

While out getting her nails done in Beverly Hills, Paris Hilton's mom, Kathy, offered Lindsay Lohan some words of encouragement.

When asked if she'd like to say anything to the 24-year-old troubled starlet, Kathy tells our videographer:

"I thought everything was going good. I didn't know there was any trouble."

After being reminded that Lindsay is due in court next month, Mrs. Hilton adds, "I wish her the best."

So sweet!

See Kathy hanging with her famous daughter Paris and beau Cy in Hawaii ... after the jump.

Just another day in the life of a beautiful socialite!

Hotel heiress turned reality show star Paris Hilton hit up The Grove last night to see Santa with her hot beau Cy Waits. The couple also came across hundreds of fans wanting a pic of Paris!

Later on, Princess P saw I Love You Phillip Morris and Tweeted: "Such a funny, cute and entertaining movie. Jim Carrey and Ewan McGregor make a hot couple! ;)"

Also along for the ride? Mom Kathy Hilton!

Looks like Cy is looking to make a good impression on his girlfriend's 'rent(s)...

Paris and Nicky out clubbing this past Thursday

Now THIS is some interesting news!

So, we spotted Kathy Hilton out lunching at The Ivy with daughter Paris on Friday, but afterward the elder Hilton headed over to the Boom Boom Room to attend a Hollywood gifting suite intended for, get this, parents and expecting parents...

A source tells X17 that Kathy's enthusiastic participation in the event was a tad, well, confusing. At different times Kathy asked her host to direct her toward newborn items related to "both boy and girl stuff" and later "twins."

Kathy also said she was "shopping for her sister" at first, but later changed her alibi to "shopping for my sister-in-law." Whoops!

The presence of Mrs. Hilton caused a lot of speculation, of course, with many concluding that Kathy really had something to hide. Hmm, but which daughter was she shopping for?

Paris has talked about wanting a lotta kids, but Nicky is the one with a serious boyfriend. If we had to choose between the two, we'd go with Nicky!

Of course, as you can see from the photo above of Nicky and her b/f at Joan's on Third a couple days ago, she doesn't really look preggers does she?

There's nothing mothers love more than being photographed with their adoring children - and if those adoring children happen to be Paris and Nicky Hilton, there's always a camera close at hand!

The Hilton sisters spent Saturday stepping out for a little shopping on Robertson with their mother Kathy. After hitting up Kitson, the famous family headed over to Nanette Lepore, where the throng of photogs on their tail managed to grow even larger somehow. At one point, Kathy even got a little embarrassed at all the attention she and her brood were receiving and tried to shield Paris from the paps - nice try, Kathy, but your oldest daughter's got a reality show to shoot!

Eventually, however, even the Hiltons ran out of stuff to buy and called Paris' main squeeze Benji to come pick 'em all up. Dutiful as ever, the punk rocker braved the paps to collect his girlfriend and her folks. Aww - how sweet!

Paris Hilton sure had a full week of gifting last week - first a birthday party for Benji, then another birthday party for Benji, and finally one last birthday party for her mother Kathy last night!

We caught up with the celebutante picking up a card for her mom from the Rite Aid yesterday afternoon. She drew a pretty considerable crowd of admirers and gawkers while she shopped - not that she minded, of course!

After a quick stop to refuel, it was over to Orso to meet up with Nicky and Kathy for a big birthday lunch. Afterwards, Nicky and Paris gave Kathy the best birthday present a mother can get - a beautiful picture with her two daughters!
