Jennifer Lopez was surprised guests at the 17th annual Latin Grammy Awards on Thursday in Las Vegas when she performed with Marc Anthony and presented him an award. However, that wasn't the biggest surprise of the evening since Jenny from the block kissed her ex-husband on the lips.

Jennifer shared with the audience that the father of her six-year-old twins is 'a living legend' while presenting Anthony with the Latin Grammy Awards " Person of the Year prize."

She said, "He's not only the person of the year, he's the person of all time."

In a separate ceremony on Wednesday, Marc dedicated his award to his five kids and to all those people who told him that he would never make it.

The former couple performed "Olvidame y Pega la Vuelta" together on Thursday and Anthony also presented his song "I Need to Know. "

Though they split 2014 after 10 years of marriage, the ex-spouses ended up working together on a Spanish language album earlier this year. Marc is currently married to Venezuelan model Shannon De Lima while Jennifer has just broke up with Casper Smart.

The collaboration was announced after their surprise duet at Radio City Music Hall in NYC in August. JLo and Marc have two kids together, eight-year- old twins Max and Emme.

This fall Marc and Jenifer have been working together in a recording studio in New York on their new album. Having that in mind, it didn't seem suspicious when on October 29, the popular singer appeared on stage with Jennifer when she was giving a concert for Hillary Clinton.

Reportedly, Marc Anthony's wife of two years has left him the day after The Latin Grammy Awards on Thursday. After the "incident", the famous singer tried his best to deny any romance with his ex-wife saying that he usually playfully kisses his friends aboard his private jet and shared the photos on Instagram. The hitmaker was trying to make it seems like the normal thing he does that with everybody.

28-year-old Shannon De Lima apparently was jealous because her husband and JLo are getting very close all of a sudden and their friendship had just grown, conveniently, with Casper Smart out of the picture.

It seems that Jennifer Lopez kissing ex-husband Marc Anthony was the straw that broke the camel and Shannon De Lima will divorce the famous singer after all.
