Jennifer Lopez Is 'The Boss,' Boyfriend Says

'It was very natural how it happened,' dancer Casper Smart tells 'Good Morning America' about hooking up with J. Lo.

Jennifer Lopez has left "American Idol" behind. Now she's focused not only on her hot summer tour with Enrique Iglesias, but also on her romantic relationship with the tour's choreographer and dancer, Casper Smart.

And when she sat down with

"For me, the biggest dream is the fairy tale. I will never give up on that dream," she explained. "It can be difficult for anybody who has to stand by my side, but at the end of the day, I know that I deserve that."

Lopez began dating Smart shortly after her split from fellow music star Marc Anthony. The 25-year-old dancer explained that their relationship just kind of happened. "It was just very natural, you know, natural how it happened," he explained. "There was nothing before, no flirting, no nothing."

At the end of the day, despite the dynamics of their working relationship, he never has to ask himself, "Who's the boss?"

"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?"

The tour is not the first time Smart and Lopez have collaborated. He appeared alongside his lady love in her Pitbull-assisted "Dance Again" video. She says that loving someone you work with can be both hard and easy.

"I have done it many times and it's difficult with some people, and some people, it's easy," she added. "Just depends on their personality."

In the midst of the tour, Lopez will drop her long-teased greatest-hits album,

and "Waiting for Tonight." The album will also feature newer tracks like "I'm Into You" with Lil Wayne and "On the Floor," which also features Pitbull.
