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!
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!
