Singer-actress Demi Lovato has reportedly split from actor Wilmer Valderrama.
The couple never publicly confirmed their romance, but were caught on camera kissing several times following weeks of speculation about their relationship.
However, it seems the union is over as insiders told eonline.com that the 12-year age-gap proved too much for the couple.
Lovato, 19, took to her Twitter page to post a string of messages relating to men issues.
She 're-tweeted' a Marilyn Monroe quotation reading, "A wise girl kisses but doesn't love, listens but doesn't believe, and leaves before she is left", before adding: "The smartest thing a woman can ever learn, is to never need a man."
Lovato has previously dated pop star Joe Jonas.
