LakersLakersLast night Rihanna went to the Staples Center to watch the Lakers defeat the Magic in overtime, but was she cheering for the home team or her friend/boyfriend Andrew Bynum?

We first broke the story that the two of them were hooking up back in March, and even though Bynum claimed they were "just friends", he's the only man (other than Jay-Z) she's been seen with since Chris!
