No animosity here!

Jennifer Lopez's ex-husband Marc Anthony, the father of her twins Max and Emme, almost 6, is not only on great terms with J. Lo, with whom he split in 2011. He is also super tight with her much-younger boyfriend, Casper Smart.

While appearing on Wendy Williams' namesake show, the singer joked that "I like them young, too," referring to his ex, 44, dating someone much younger. Smart, a choreographer, is 26. But he is certainly on Anthony's good side.

"I'm not one to judge," Anthony, 45, continued.

He has actually been a fan of Smart since Day One and considers him a bro. He continued, "It's great. As a matter of fact, we were texting back and forth two days ago. We're actually really, really good friends. From the very beginning."

Lopez and her ex remain close, so the fact that Anthony gets along with Smart is paramount, since he is protective of La Lopez. "When you love someone and you care for someone... Jennifer and I -- I don't say it lightly -- we're great friends," Anthony mused. "You know, anybody that means anything to her means something to me. That's keeping it simple. Casper's a great guy. He's been great to my children. And I have nothing but respect for him, absolutely nothing but respect."

What an evolved way of thinking and behaving. Most exes aren't able to get over that hump and wish their gorgeous former wife happiness with someone who isn't them! But Anthony does.

As for his romantic status? Anthony is currently single. He and GF Chloe Green split after a year of coupledom. Like La Lopez, he is not sour on love or the concept of marriage just because theirs did not work.

"Yeah, I do, I do [want to get married]," Anthony said. "I believe in relationships. I believe that God has blessed me in so many ways... Success goes but so far. But when your house is empty and you don't have someone to invest in, if you don't have a witness, it's almost worthless."

We're sure there is a line of ladies willing to date Marc Anthony!
