Marc Anthony has called it quits with his Venezuelan model girlfriend Shannon de Lima, his rep confirms to E! News.

The couple, who had been dating a little more than a year, gave no reason for their breakup. This was the Latin singer's first major relationship since his split with ex-wife Jennifer Lopez.

Don't count on a reconciliation, though!

J.Lo is happily in love with boyfriend Casper Smart, who has been a constant companion of the former American Idol judge since they revealed their relationship last year.

We doubt Mr. Anthony will have trouble finding another sweetie!
