According to Smart's personal website caspersmart.com, he had a role in Honey 2 and was a dancer in Step Up 3D. His special skills include "krumping, acrobatics, breaking [and] popping." The 5'8" star lists his weight as between 160 and 170 pounds, and he was one of Beyonce's dancers during her 2010 Grammy Awards performance. He even played one of the "Single Ladies" dancers in a 2010 episode of Glee paying homage to Jay-Z's wife.
According to his site, he was an alternate dancer for Michael Jackson's "This Is It" world tour. The rehearsals, interviews and backstage footage of the tour were made into a 2009 film following Jackson's death in June of the same year.
Lopez, 42, has only been romantically involved with Smart for a few weeks, but an insider says their relationship is "nothing serious." Earlier this month, the duo was snapped trying to remain incognito in NYC.
Smart has also been one of the American Idol judge's dancers, according to his Twitter page. "In San Fran about his the stage with JLO!" he wrote Friday. "[With] JLO and the dope JLO dancers. LEGGO!"
But this isn't the first occasion the mom of twins (3-year-old Emme and Max) has been attracted to a fellow dancer. She married Judd, a dancer on the set of her "Love Don't Cost a Thing" music video, in Sept. 2001.
The marriage, however, ended in 2002; the same year, Lopez and Ben Affleck began a public romance. Lopez and Affleck, 39, got engaged in Nov. 2002, but split in Jan. 2004. (Affleck married Jennifer Garner in 2005 and the couple are now expecting their third child.)
After separating from Anthony, 43, following seven years of marriage, Lopez moved on with Bradley Cooper. A source told Us the Hangover star, 36, was "really trying to woo Jennifer in a big way" and the actor had been "after Jennifer, calling her, for ages." In addition to a super romantic candlelit Sept. 10 dinner at NYC's Per Se eatery, the charming Limitless actor stepped up his seduction game again with a secret flight to Boca Raton.
