Although Jennifer Lopez walked alongside her new main squeeze Casper Smart when she approached the set of Late Show With David Letterman, she talked about her ex, Marc Anthony.
The 42-year-old American Idol judge was there to promote her new show with Marc, Q'Viva! The Chosen. She mentioned "I believe in love" when asked about her marriages but when it came down to work, she opened up even more.
"It's fun because we know each other so well, but it has its moments. The same things that… didn't really work out sometimes come up." J. Lo added, "You're talking and you don't agree on something and you're like, 'Oh, be quiet!'… you'll see it on the show a little bit!"
Their show premiered on Univision this past Saturday night to the tune of 2.2 million viewers!
