These hook-ups have people scratching their heads.
This is a hot week for celebrity lovers! There must be mistletoe dangling all over the place due to the upcoming holiday, because these stars are getting into some serious smooching action!

Everybody is talking about Jennifer Lopez and her boy toy Casper Smart, who put romance rumors to rest with a lip-locked CONFIRMED stamp once pics of the two making out during a break from dance rehearsal hit the internet!

Keen eyes spotted J.Lo’s wedding ring still on her finger, even though she has apparently moved on to younger pastures. Cougar alert!

During the Rockefeller Tree Lighting in NYC, Twilight beauty Ashley Greene and her boyfriend, “Spider-Man: Turn Off the Dark” star Reeve Carney, shared an affectionate kiss while keeping each other warm. Get a room, these two! 

Meanwhile back in Los Angeles, Anne Hathaway and boyfriend Adam Shulman were caught kissing as they left a friend’s house — while Jennifer Garner and hubby Ben Affleck kept it PG in front of their eldest daughter Violet while the family went for a stroll in Santa Monica, CA, when he planted a sweet peck on her cheek.
