Jennifer Lopez confirmed Tuesday she is back together with her boyfriend, actor-choreographer Beau “Casper” Smart, but that marriage is not in her immediate plans.

“Beau was working down there,” the pop star, 46, said of their spending New Year’s weekend together in Miami, telling talk-show host Ellen DeGeneres, “He was working. I didn’t have to work — I had, like, literally two days off. And we just, we were hanging out.”

Lopez said she gave Smart, 28, a tuxedo for Christmas, “became I’m opening in Vegas, and I was like, ‘You could wear this on opening night so you look nice.’ ”

When DeGeneres suggested the tux could be for a wedding, Lopez gamely answered, “No. No wedding. . . . There’s no wedding. . . . No. No. OK?”
