What should I do?

[Mr. Bubbles]

My cousin, who I hang out with a lot, is going out with this girl who I'm friends with. Shortly after they got together, someone was saying that he had slept with this other friend of ours. He told me it wasn't true, and I believed him and told the girl he's currently going with that I didn't think he did. Well, he was using my MSN tonight so I was checking my chat history with people and saw a convo between him and this other chick that he was accused of sleeping with. It turns out he did, and I don't know what to do about it. Should I keep it to myself? Should I tell his current girlfriend? Should I confront him? I don't know what to do but I'm kind of pissed that he'd lie to me, but his girlfriend is also a good friend and she trusts me. Also, anyone who says 'bros before hos' can just not post here because I consider myself an honest guy. His girlfriend will probably find out one way or the other, but I'm almost positive he'll get major upset with me.
