Paris Hilton jetted to Colombia on Tuesday to open her new handbag and accessories store, and she's already on her way home, but before packing her bags yesterday she spent several hours with the kids at La Fundacion Cardioinfantil.

A source close to the heiress tells X17online, "They were all so happy and excited to see her. She brought a huge bag full of presents for the children, and some of the moms were crying from happiness saying how grateful they were for her to come and see them. This is a hospital for underprivileged kids, and the foundation takes care of their treatment and stay." Awww!

P tweeted, "Nothing feels better then making someone smile & bringing happiness to their life. #Love #Children ... Loved spending time with all the kids at the Children's Hospital @FCardioInfantil today. Loved seeing them smile. Such sweet angels."

We love it when celebs have a heart of gold!

Paris Hilton and boyfriend River Viiperi arrived at LAX early this morning to catch a flight to South America.

Paris Hilton and boyfriend River Viiperi headed to Coachella for a second weekend of music and partying and the Queen P was exciiited!

Just in case you forgot her name, it's written on her shirt!

A lot of women her age are settling down and having children, but Princess P is way too busy partying for that! Just yesterday evening the 32-year-old tweeted she was packing for Coachella, and clearly she's a big fan of the desert music festival, because she attended last weekend too!

Somewhere out there, Kim Kardashian is green with envy thinking about the socialite's carefree lifestyle!

On Wednesday Paris Hilton was snapped after stopping by Anastasia in Beverly Hills, and after some business meetings at the beginning of the week, it looks like the heiress is ready to unwind ... and ready to get her party on at Coachella this weekend!

Aside from hanging out with beau River Viiperi and playing with her pets, P has been spending quite a bit of time at the pool lately, but she's not just working on her tan! "I love swimming," she tweeted the other day. "It's fun & such a great work out."

Don't worry P, you look fabulous from every angle!

Any occasion to play dress-up is a good time for Queen P!

Paris Hilton threw on a hot pink bunny suit to celebrate Easter at the Playboy mansion over the weekend, and the heiress cozied up to none other than Hugh Hefner at the bash!

"The Easter Bunny with Hef. Love you @HughHefner. Happy Easter!" she captioned the above snapshot of the pair.

The Simple Life star flew back to L.A. just hours prior, but clearly she didn't let a little jetlag keep her from partying with playmates!

At 32-years-old, you would think the blonde beauty would be ready to settle down and put her wild lifestyle behind her!
