Kanye celebrates 36th birthday: Kim misses party, Beyonce shows midriff Instagram / @KimKardashian To celebrate his 36th birthday, Kanye West had a bash in New York City. Pregnant girlfriend Kim Kardashian was unable to attend, but showed him some love on Twitter. With the tweet, she Instagrammed a photo collage of "Kimye" in love. Kardashian and West are expecting a baby girl in July. Because of the pregnancy, Kardashian's doctor has advised her not to fly, so she had to miss the fete. She tweeted earlier this year that she wouldn't be able to fly after her May trip to Paris. The party was at Ms. Lily's in New York City. At the party, Beyonce arrived wearing a midriff-baring top that quieted some of her own pregnancy rumors. She paired the striped body-con ensemble with orange heels and black sunglasses. Other guests included West's rapper friend Nas, Kourtney Kardashian with boyfriend Scott Disick, and Kim's good friend Jonathan Cheban.
