Rihanna rihannahouses.jpg

This afternoon Rihanna went house-hunting in the Hollywood Hills, checking out homes near other celebs like Leonardo DiCaprio, Nicole Richie, and Cameron Diaz! Ri even looked at Christina Aguilera's old home - we're not talking 2br, 2ba here, people - Miss Disturbia's lookin' at some MANsions!

It's interesting too that she's apparently looking to leave her quite Los Feliz neighborhood behind and move straight into the heart of Hollywood -- the famed hills above Sunset Blvd, just minutes away from all the shopping and nightlife LA has to offer.

But the question everyone wants to know is ... will she and Chris be shacking up???
