The sexy star hit the landmark age on 21.10.10 and rather than be worried about entering the new decade of her life she is very excited.
Accompanied by a picture of her with her friends, she wrote on her twitter page: "UH OH The big 3-0!!!! Why does everyone call it The Dirty 30? Its The Flirty 30 to me! LOL (sic)"
Kim has also been bowled over by all the happy birthday messages she has received from her followers on the micro-blogging site.
She added in another tweet: "I woke up to the sweetest bday messages! Seeing all of your tweets will make me smile all day! I love u guys!!!! (sic)"
Kim was celebrating in New York with friends when the clock struck midnight and she stopped being 29.
Before the actual date, the beautiful socialite had three parties to celebrate the milestone age taking place in Las Vegas, New York and Toronto respectively.
In Las Vegas she partied at exclusive nightspot Tao on October 15 and was presented with a cake, and she received another baked treat while enjoying a birthday meal at a New York restaurant on October 18.
While at Sherway Gardens in Toronto, Canada, she was surprised with a pink and black three-tiered cake adorned with a picture of her on it.
