Exes With Benefits? Jennifer Lopez Kisses Ex-husband Marc Anthony Onstage At Latin Grammy Awards (Pics)

Jennifer Lopez surprised guests at the 17th annual Latin Grammy Awards on Thursday when she presented an award to her ex-husband Marc Anthony and also performed onstage with him.

Perhaps the biggest surprise was not only the lavish praise she showered on him but a tender kiss on the lips.

She described the father of her six-year-old twins as 'a living legend' as she presented Anthony with the Latin Grammy Awards' Person of the Year prize.

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

Anthony, who was feted in a separate ceremony on Wednesday, dedicated his award to his five children and 'to all those people who told me I would never make it.'

The former couple performed Olvidame y Pega la Vuelta together onstage.
