Jennifer Lopez kicked off the North American leg of her worldwide tour in Montreal this weekend, and Good Morning America caught up with the pop star and her 25-year-old choreographer beau Casper Smart to get the inside scoop on their relationship, on and off the stage. “Sometimes, I tell her something, give her notes,” Smart said of working with his famous girlfriend. “But at the end of the day, it doesn’t matter what position is what, because she’s the boss.” Lopez loves performing alongside her dancer beau, and she even hinted to GMA that wedding bells could always be an option. “For me, the biggest dream is the fairy tale,” she said. “I will never give up on that dream.” Watch more of the interview tonight on Nightline at 11:35 ET on ABC.
