Rihanna's Painting Purchases

Rihanna poses with friends at the Grove’s Jack Gallery in Los Angeles on Saturday night.

The “Umbrella” singer, who turned 20 yesterday, purchased seven paintings by pop cartoonist Todd Goldman as an early birthday present for herself, including the one she is photographed in front of, “Fat Kids Are Harder To Kidnap.”

“Half of the paintings are going to her house in L.A. and half to her apartment in NYC,” a source exclusively tells JustJared.com.

Rihanna also picked up other pieces of artwork including “Goodbye Kitty in a Microwave,” “Gold Digger Like a Hooker Just Smarter,” “My Mom Says Not to Run Scissors,” “Barbie is a Slut,” “A Salt with a Deadly Weapon,” and “Smurf Blue Balls.”
