All the details from Kristen’s big night out in Hollywood!

Kristen Stewart, 19, left all her angst at home last night. She helped celebrate the opening of new Hollywood club La Vida, and she couldn’t have been more fun as she laughed and partied the night away with her crew of hipster boys. But don’t worry Rob Pattinson, they’re all just friends!

Kristen showed up just before 9 p.m. and hit the red carpet looking cute in all black (OK, so her outfit may have been a little emo) before heading inside and taking her seat by a big fireplace. She immediately looked totally relaxed and at ease as she sipped what looked like iced tea (no beer for this 19-year-old!)

After settling in, a man brought his daughter over to Kristen so she could meet her, and Kristen looked genuinely happy to oblige. The girl’s face as she walked away from her idol was one of the cutest things we’ve seen in a while. Another cute moment from the night was when the club started playing Joan Jett‘s “I Love Rock ‘N’ Roll” and Kristen totally rocked out a little bit to it, while her friends let out a few cheers.

The only objection we had to Kristen’s big night out was all the chain smoking she did! Kristen, you’re just 19 years old and you’re such a pretty girl — PLEASE give up that nasty habit! You may think it’s cool now, but trust us, years from now you’ll wish you had used your head.

We saw a brand new side of Kristen last night. She’s a total LA girl — part hipster, part glam-goddess — and it’s obvious to us what Rob Pattinson sees in her now. If only she’d lose the ciggies!
