Jennifer Lopez hit the red carpet with her boyfriend, Beau "Casper" Smart, last week, and now it's her ex's turn in the spotlight.

Marc Anthony stepped out with his new girlfriend, model Shannon De Lima, 24, over the weekend at the 27th Annual Cedars-Sinai Medical Center Sports Spectacular, looking as lovely as ever.

However, this isn't the first time the couple has hit the carpet together. They were photographed at the 2012 Billboard Latin Music Awards last month after taking their relationship public earlier this year.

The singer split from wife Jennifer Lopez in July 2011, but the couple have managed to continue working together on their reality show, "Q'Viva: The Chosen," and are set to perform together in Las Vegas this year.

Smart, who will choreograph Lopez's upcoming world tour, recently spoke to the press and put to rest rumors he and the "American Idol" judge got together before her split, while Lopez opened up about her relationship with Anthony.

"Marc and I were friends for 10 years before we got married," Lopez told E! at the premiere of "What to Expect When You're Expecting." "We got married, we had two beautiful children, and we're still friends," she said, adding that she and Anthony will perform in Las Vegas together with the "Q'Viva" crew. "Things disappointingly don't work out the way that you dream them in your mind sometimes. That's life."
