Any guesses why this Jen is popular among the guys? No, it's not the dance moves, although we agree she is a sexy dancer! Remember the song Jenny from the block? And remember the, oh so lucky Ben Affleck, rubbing sun tan lotion on that famous butt? Yes, it's the butt that can probably balance a tea cup on it. 

Born July 24, 1970, Jennifer Lopez has worn many hats, and raked in the "bling" and not the mention the moolah. From being dancer, songwriter and singer/performer, she went on to be an actress (remember the Wedding Planner?), producer and now even has her own show called Dance Life.

Her romance with Hollywood cutie Ben Affleck caught all of our fancies! They were the media darlings…until it all fell apart! (Tut tut!)

But we hear she and hubby Marc Anthony are doing great and she is getting ready for motherhood. Twins, we hear. Way to go momma Jen!

Did you know: Jen was a dancer in Janet Jackson's troupe before she made it big? Check her out in the Janet Jackson hit song That's the way love goes.
