WATCH: CBB contestant Heidi Montag's performance on Miss Universe 2009

Oh and that time when her husband Spencer tried to rap on her song too...

As Spencer Pratt and Heidi Montag entered the Celebrity Big Brother house, they made a quick reference to Heidi's 2009 performance on Miss Universe.

Naturally, there's a new interest in that clip and we have to admit it's definitely fun to watch.

But what's even better is the version of the single which features a rap from her husband, Spencer Pratt. Oh these two are a hoot!
