Kim Kardashian partied with pals last night in Celebration of her 30th birthday today (21.10.10).

The socialite spent the evening with her closest female friends Las Vegas, where they celebrated her reaching the landmark age with a "flirty" girls' night out.

She tweeted: "Why does everyone call it The Dirty 30? Its The Flirty 30 to me! LOL (sic)"

The brunette beauty has had a busy time recently in the run up to her special day, with plenty of parties and photoshoots.

Curvy Kim recently posed nude for W Magazine, and although she was thrilled with the results she has vowed never to strip off again.

She said: "It turned out beautifully, and I love it.

"But I don't know if I'll pose nude again. I'm too old for that now... I wanted to get it all out of my system before I turned 30."

The 'Keeping Up With The Kardashians' star also admits she finds getting older "nerve-wracking".

She said: "It's nerve-wracking because now when someone says 'How old are you?' I have to say 30. It scares me a little bit. But I do feel accomplished, and I feel like I've gotten a lot done before 30. I feel good!"
