WHOA -- Jennifer Lopez Kisses Ex-Husband Marc Anthony In Front of Millions!

Ai yai yai!

Jennifer Lopez just slapped a big kiss on ex-husband Marc Anthony in front of millions of people during the 17th annual Latin Grammy Awards!

J-Lo was at the Las Vegas event to present Anthony with his Latin Grammy Awards Person of the Year prize. The duo performed Olvidame y Pega la Veulta, and Anthony would later perform I Need to Know solo.

Lopez was full of praise for her ex during the ceremony, calling him “a living legend” and saying, “He’s not only the person of the year, he’s the person of all time!”

But the moment that has the world talking is the soft kiss shared on stage. Make of that what you will!

The former couple shares two children, 8-year old twins Max and Emme. And while they haven’t been an item for some time – Anthony is married to Shannon De Lima, and Lopez recently split from Casper Smart – they do still work together. The two announced a Spanish-language album to be released in 2017.

“I am so excited and really looking forward to this new musical journey and to celebrate my Latin roots with Marc,” J-Lo said in a statement. Anthony added, “[Lopez] has had enormous accomplishments in her career and has been representing our culture all over the world from day one. Her artistry, professionalism and passion for music are just some of the many attributes that have earned her a unique place in the entertainment world that very few people have been able to obtain.

“I am looking forward to our creative collaboration and to be part of continuing her musical legacy.” 

But enough about the music -- what do you think of the big smooch?!
