Casper Smart, Jennifer Lopez's Boyfriend, Opens Up About Falling For The Superstar

Casper Smart, Jennifer Lopez's boyfriend, says it wasn't exactly love at first sight when he initially met the superstar.

The 25-year-old dancer opened up about his famous flame on Tuesday, telling "Good Morning America" that his relationship with Lopez, 42, was a slow, gradual process.

“It was just very natural, you know, natural how it happened,” Smart told ABC News' Amy Robach in his first sit-down interview. “There was nothing before, no flirting, no nothing.”

It's not the first time Smart has talked about his relationship with Lopez, who he began dating months after she and husband Marc Anthony called it quits. In a red carpet interview with E!'s Marc Malkin in May, Smart said that the relationship "was really professional for a very long time before anything even happened... It just really spontaneously happened. The chemistry was there. You can't fight it."

Smart, who is 17 years Lopez's junior, also talked about the experience of working as the lead choreographer on the singer's current world tour with Enrique Iglesias.

"Sometimes, I tell her something, you know, give her notes. But at the end of the day, you know, it doesn’t matter what position is what, because she’s the boss, you know?" Smart said.

Meanwhile, Lopez told Robach that she hasn't given up on marriage, an admission that comes months after the star told People that having more children would be "a blessing."

"Yes, for me the biggest dream is the fairytale," the three-time divorcée said. "I will never give up on that dream."
