For Smart's 25th birthday back in April (the same month J. Lo's erstwhile husband Marc Anthony filed for divorce), Lopez bought the youngster a Dodge Ram truck, and now she's giving him a new job as choreographer for her upcoming 20-date tour with Enrique Iglesias and Wisin Y Yandel.

Lopez announced the move during a press conference about the tour, her first (in her mind, anyway), on Monday (April 30), revealing that her young beau would be composing her moves.

"I'm working with Jamie King -- also Beau 'Casper' Smart is my new choreographer," she said, with a slight flush.

Despite his close relationship with the star, Smart's appointment is not without merit -- he recently appeared opposite Lopez in the steamy "Dance Again" video, and has previously choreographed for Beyonce, Kelly Rowland and popular shows "So You Think You Can Dance," "America's Best Dance Crew" and "The X Factor."

Though the tour, which kicks off July 14, will be a grueling six weeks, J. Lo has revealed that she will also be bringing along her 4-year-old twins, Max and Emme.

"Obviously, we're going in the summer so they won't be in school at that time, so they're going to come with mommy on tour," Lopez said. "I don't know how that's all going to work. Hopefully, there's always grandma's house if they get really tired and stir crazy. But, I can't be away from them for too long."

While fans await her tour's July 14 launch, they can check out J. Lo on "American Idol," and the Las Vegas stage debut of her own competition show, "Q'Viva," on May 26.

Tickets for the tour go on sale Friday (May 4).
