Come On Barbie, Let's Go Party!

Paris Hilton was spotted in Bel Air the other day doing some shopping, but it looks like it wasn't for her! The heiress purchased Barbie cereal (so appropriate, right?) and several other items which were carefully gift wrapped - wonder who's getting presents from Paris?

And what's with the ring Paris is rocking on her engagement finger? Think Benji got her a present?
