Jennifer Lopez has bounced from honeymoon to freedom fighter, headlining a UNICEF concert to help in the Ukrainian relief effort.
J Lo took the stage at a 14th-century monastery in Capri, and she looked pretty incredible in a zebra-print getup with feathers and glitz. And this is a shocker ... she showed off her abs, which is always a gift!
Jen wasn't done ... the next outfit was a nude thong bodysuit ... again, pretty incredible.
JLo was the headliner, following Diplo, Sofia Carson and DJ Cruz.
There were tons of celebs on hand ... Leo DiCaprio, Naomi Campbell, Jamie Foxx, Jared Leto, Vanessa Hudgens and Maye Musk. Jennifer's bro-in-law, Casey Affleck, was also there with his gf Caylee Cowan.
No sign of Ben ... as far as we know, he's back in L.A. -- recovering from his honeymoon!
