The couple enjoyed a smoochy PDA before sharing the stage at the American Music Awards last week, and only a few days later, Casper accompanied Jen and her kids on a holiday to Hawaii!
Looks like things are moving fast for the singer and her, erm, bad boy squeeze. Casper (real name Beau) was arrested in 2010 for drag racing and after failing to show up at hearings, he's now facing jail time.
But all that jazz is no concern for 42-year-old Jen, who happily looked on as Casper played with her twins, 3-year-olds Max and Emme, on their beach vacation.
We wonder what her ex-hubby and baby daddy, Marc Anthoy, thinks about all this cavorting around? Especially when Jen's new man is about half his age!
