Forget the ex-wives club. Jennifer Lopez‘s exes are forming a club of their own. Casper Smart and Marc Anthony reunited for an epic selfie — and fans were really confused about Casper and Marc’s seemingly newfound friendship.

“If you’ve never seen his show you are really missing out. A Truly captivating performer! Thanks for taking care of my people and I @marcanthony much appreciated,” Casper, 30, wrote after attending Marc’s concert in Miami over the weekend. The duo was all smiles in the pic, but some followers believed they were being a little bit petty.

“Si yo fuera J.Lo, no sabría que hacer,” one fan wrote in Spanish, which translates to, “If I were J.Lo, I wouldn’t know what to do.” Another added, “This is weird. They both messed with J.Lo lol wow but whateva.” While we agree it is a bit weird to see Casper and Marc together, both men have been very open about their relationship with the “Love Don’t Cost a Thing” singer following their respective breakups.

Casper and Jennifer, 48, dated for five years before calling it quits in 2016. In that time, he got really close to her nine-year-old twins Max and Emme, which she shares with Marc, 49. “[We’re] friends,” Casper told ET before, adding that the exes have “nothing but respect and love for each other.”

He continued, “I want nothing but the best and love [for her].” J.Lo has also gushed about her ex-husband in the past — and revealed that they are working together on her upcoming Spanish-language album. “Marc and I are good how we are right now,” she said on The View. “There’s a reason we’re not together, but we’re great friends. And we’re parents together. We’re even working on a Spanish album together. [And] that has been even better for us. We met working, and that’s where we’re really magical when we’re on stage together, and so we leave it there. That’s it.”

All that’s missing is Ben Affleck— and this would be perfect!
