Photos: Nicki Minaj turns 30, her cake? O.M.G

   

Nicki Minaj turned 31 years old yesterday and she celebrated with two voluptuous helpings of boob cake!

After arriving in a hot pink Lamboghini, the rapper strolled into Philippe restaurant in Bev Hills last night where she partied with friends.
The sweet treat read "Shake your ... for Nicki".
