Jennifer Lopez and Casper Smart Jump Into Zimbio's 100 Hottest Couples

, she's used to appearing with Marc Anthony. Well, after their split, JLo rebouned in a big way with yet another of her backup dancers, Casper Smart. Their first time on the list sees them at number 35.

Jennifer Lopez and her ex-husband, Marc Anthony, rounded out the top 10 on last year's list. A lot has changed since then. The couple split in July 2011 and by the time Thanksgiving rolled around both stars had found hot 24-year-old rebounds. Lopez's new man, Casper Smart, was just a co-worker essentially. Now, he's traveling the world with her (not in a bus) and she even bought him a tricked-out truck for his birthday. The tattooed dancer also starred in Lopez's music video for "Dance Again." That said, the odds of this blazing hot romance keeping the heat aren't exactly high.

For those curious about our process of ranking these couples, this year we've refined our definition of "hotness" to rank 100 celebrity couples using the following criteria: Staying Power, Popularity, Success, and Attractiveness. The resulting list includes hot pairings made up of models, singers, actors, ex-wrestlers, reality stars, and more. While the hottest couple of them all, Beyonce and Jay-Z, has been on our list for four years now, 24 of these famous duos also made their debut. Check out the entire feature here.
