Rihanna And Chris Brown Ice Each Other

Rihanna and Chris Brown are doing a bad job of pretending they're not a couple. The two were practically in one seat at last night's MTV Movie Awards. Plus when you're treating your "friend" to diamond necklaces, the jig is up.

Rihanna and Chris have decided to celebrate being together by giving each other $200,000 diamond necklaces. They purchased them recently at jeweler Jason Arasheben's exclusive Beverly Hills store.

Rihanna's necklace has a heart on it, and Chris' is a diamond-encrusted cross. So what's the one-year anniversary present? A room full of gold coins and a diving board?
