Demi Lovato has split from her boyfriend Wilmer Valderrama. The former Disney actress tonight tweeted a link to a news article about them going their separate ways - apparently confirming the rumours. The 19-year-old star and 31-year-old Wilmer - best know for his role in That '70s Show - started quietly dating again back in November after previously being linked together.

They were spotted sharing a public clinch shortly after Demi entered rehab for eating disorders and biopolar disorder. On Monday night the actress-turned singer hinted all was not well with a string of tweets. 'Loyalty is EVERYTHING.. I’m thankful for my friends who stand by my side,' she posted. It was followed by a retweet of quote from Marilyn Monroe, which one of her followers sent to her: 'A wise girl kisses but doesn’t love, listens but doesn’t believe, and leaves before she is left.'
She then wrote: 'The smartest thing a woman can ever learn, is to never need a man.'These tweets have since apparently been removed. Demi is now focusing on her music career after saying she found it too difficult to see herself. She will be performing tomorrow night at the People's Choice Awards.
