If only he had her love again. When Marc Anthony planted a kiss on ex-wife Jennifer Lopez at the 17th annual Latin Grammy Awards on Thursday, November 17, the sign of affection may not have been platonic.

The Latin singer is "still in love" with Lopez, 47, a source exclusively reveals in the new issue of Us Weekly, and he "is trying to get back together with her." Find out more in the video above, and from details below.

The exes, who split in July 2011 after seven years of marriage, are both recently single. Anthony, 48, separated from his third wife, Venezuelan model Shannon De Lima, earlier this month, and the Shades of Blue actress ended her on-and-off four-year relationship with choreographer Beau "Casper" Smart in August. 

Though sources tell Us that Anthony's marriage to De Lima, 28, had long been troubled, the insider says, "As soon as he heard Jennifer split with Casper, he wanted out."

It may be music that's bringing them back together. The parents of 8-year-old twins Max and Emme are currently collaborating on Lopez's untitled Spanish-language album, which Anthony is producing. The duo "have magic when they sing together," says the pal. "That's how they came together last time. There is just this chemistry between them."

That chemistry was evident at the Latin Grammys. The former spouses sang a Spanish duet of “Olvídame y Pega la Vuelta," which will be on their upcoming album. After their performance, the star of the Las Vegas residency All I Have presented Anthony with the Person of the Year award, and as the crowd chanted “beso” — meaning “kiss” in Spanish — they locked lips. In her speech, Lopez said: “Marc is a living legend. He is a magical and pure artist giving away classics that will stay forever. He will always be many things in my life.”

If he has his way, Anthony's new role would be as her lover. And though a Lopez source insists the "Ain't Your Mama" singer is "happily single" and has "no plans" to rekindle the romance with her ex-husband, the source concedes, "She did make beautiful music with Marc!"
