VIDEO: Are Jennifer Lopez and Ben Affleck getting back together for good?
Jennifer has a close relationship with the NBC daytime show and is good friends with host Hoda Kotb, who wasted no time in asking her.
Hoda told J-Lo that every time she saw photos of her and Ben, she thought that the singer looked very happy. However, Jennifer focused her answer to the very thing she was on the show to promote - her new song, Love Makes the World Go Round.
Jennifer has collaborated again with Lin -Manuel Miranda on the new song, and she replied to Hoda: "The song is out, five years since we've done it. And I believe that that message of loving one another and coming together and love, is never more relevant than it is right now."
"Wait, it's me you're talking to, you know that," Hoda replied. "I know," Jennifer said. "You can call me. You have my number!"
It was via Today that the star and A-Rod announced their split. Jennifer's daughter Emme also appeared on the daytime show via video link in September to chat about her debut children's book, Lord Help Me.
Most recently, Ben was pictured out in LA with Emme, and his two youngest children, Seraphina and Samuel, who he shares with ex-wife Jennifer Garner.
