What does Rihanna spend her money on? Tattoos, of course. But, she also has an eye for art and has recently commissioned British artist Claire Milner to produce a portrait of Marilyn Monroe, apparently the singer's idol, from 65,000 Swarovski crystals. The work follows an earlier, although smaller (just 5,000 crystals), portrait by Milner of Monroe. The artist says the deal was done through Rihanna's interior decorators. However, Milner also says the superstar loves her new bling. [Minute 15 via Art Info]
