Kim Kardashian, Kanye West

Kim Kardashian and Kanye West had a lot to celebrate on New Year’s Eve! The day before, the rapper announced to the world that his reality TV star girlfriend is expecting with their first child. Although there is a technicality to work out – she’s married to someone else! – the K couple was in a celebratory mood at 1Oak nightclub at the Mirage in Las Vegas, where she was hosting the evening’s festivities. After doing the countdown – and telling partygoers, "Have a drink for me please, because I can't for a little while" – she planted a hot smooch on her baby daddy and hugged him for an extended embrace.
