Jon Seda 1
We know we're not the only ones who fell in love with Jon Seda when he starred as J.Lo's love interest (guitarist Chris Perez) in the 1997 biopic Selena. Ponytail and all, Jon is a SUPER handsome guy!
George Clooney 2
Long before she hooked up with Marc Anthony and even long before there was "Bennifer," La Lopez starred in the 1998 film Out of Sight opposite newly engaged George Clooney. In the film, which is considered one of her best roles ever, Lopez played Karen Sisco, a U.S. Marshall who has the hots for a bank robber (played by Clooney) whom she's supposed to arrest.
Matthew McConaughey 3
In the 2001 rom-com The Wedding Planner, Lopez played Mary, a successful wedding planner who falls madly in love with the fiancé of her biggest client--who was played by the delicious and charming Matthew McConaughey!
Ben Affleck 5
J.Lo has a habit of working with her boyfriends/husbands in movies (see El Cantante) and Ben Affleck was no exception. During their crazy "Bennifer" years, the power couple starred in two films together: 2003's Gigli (which is widely considered one of the worst films ever made) and the successful 2004 romantic comedy, Jersey Girl.
Michael Vartan 6
In the hilarious 2005 movie Monster-in-Law, about a mom (Jane Fonda) who tortures her future daughter-in-law (Jennifer Lopez), the dreamy Michael Vartan (Alias, Never Been Kissed), plays Lopez's fiancé. She got to kiss him over and over and OVER again. We're jealous!
Marc Anthony 7
In the 2006 biopic El Cantante, based on the late salsa singer Héctor Lavoe (played by Marc Anthony), Lopez played Nilda Georgina "Puchi" Roman (Hector Lavoe’s wife). The two were still married when they starred as lovers in the film.
Alex O'Loughlin 8
The 2010 rom-com The Back-Up Plan told the story of a single woman (Jennifer Lopez) who gets artifically inseminated on the same day that she meets the love of her life. Lopez's love interest in the film was played by the ruggedly handsome Alex O'Loughlin (Hawaii Five-0).
Rodrigo Santoro 9
Remember Rodrigo Santoro as Laura Linney's sexy love interest in the rom-com, Love Actually? Well, the Brazilian hottie was equally hot as J.Lo's on-screen husband in What to Expect When You’re Expecting (2012), based on the pregnancy guide of the same name.
Ryan Guzman 11
In the upcoming thriller The Boy Next Door (due out in 2015), Lopez plays a woman who has an affair with her teenage neighbor. The neighbor will be played by the unbelievably hot Ryan Guzman, who is best known for his roles in the Step Up franchise. Well done, J.Lo!
