We aren't the only ones laughing at the new rumors that Dancing with the Stars pro Maksim Chmerkovskiy is dating superstar Jennifer Lopez -- apparently, his ex fiancee Karina Smirnoff finds the new twosome just as hilarious was we do.

When asked if she was mad at Jennifer Lopez for dating ex fiance Maksim Chmerkovskiy, she broke out in to laughter, smiled and said, "Congratulations to both."

The Ukrainian beauty, who was wearing white pants and a black top, touched down at LAX on Thursday, and was greeted by a hunky mystery man. With a man like that at her side, it's no surprise that she and Maksim are on such good terms.

When pressed about the new couple, the 36-year-old dancing queen added, "That's awesome good for him. She's great!"

Heck yeah, J.Lo's great -- too great for Maksim!

We aren't over the moon about this pairing (who hasn't Maks dated?!), but we know Jenny from the block loves her dancing men -- and maybe this one won't have a hunger for transsexual models.
