randb or rap

Here are some details... not sure if this is going to help but try and think its pretty old i guess, probably late 90's-early2000's people dancing on the dance floor.... in a gym, lots of hot girls in the video, but morely the song is good.. its in my head but cant think of it.. ahhhhh...

Here are some lyrics... Now she so bad, shes my lover shes my wifey, shes so bad make me wanna treat her right.. i have no idea what song this is and its driving me crazy!

This was maybe 2003-2005 and it was a very popular song. It was played on radio stations. It was a man singing. It was a really big insult song about a girl cheating on him I think. Then after this song a girl came out with the girl's version of it.
