Jennifer Lopez kind of surprised her boyfriend who just celebrated his 25th birthday with a big banging gift.

Last weekend Casper Smart a.k.a. Jlo’s very young boyfriend celebrated his birthday and his gift was big truck to which the two went in and drive away from the scene of the party.

The party was attended by friends of Jlo like Benny Medina and “American Idol” judge Randy Jackson and of course Jennifer Lopez herself who went sported a turquoise dress baring her cleavage all the whole time.

Casper Smart might be 15 plus years younger than Jlo but if you check out their pictures together you really can’t see the age difference at all!

By the way, it was a nice party for a lucky dude, who got an awesome girlfriend plus an awesome gift!
