DEMI LOVATO

Could it be sexual tension between two 'X Factor' judges? From questioning each others' personal lives, to their flirty chumminess, we're here to tell you what's going on.

The fact of the matter is, some celebs just plain ol' look better with a little meat on their bones. Men are always telling us that they find curves incredibly sexy, and the truth can be seen in stars like Nicki Minaj and

There are plenty of theories about why relationships in Hollywood don't last, but we haven't considered this one yet: the stars just don't want them to!

It looks like the relationship between Demi Lovato and former That 70s Show star Wilmer Valderrama may have crashed and burned... again. According to HollywoodLife, the 19-year-old singer, who recently won "Favorite Female Pop Artist" at the People's Choice Awards, and the 31-year-old actor have broken up due to issues stemming from their 12-year age difference.

Demi Lovato and Wilmer Valderrama broke up in June, but now it seems that they've been able to put whatever differences they had behind them and look toward the future.

Gross. Gross, gross, gross. Rumors are swirling that Ryan Phillippe and Demi Lovato have been secretly dating now for a few months. Ryan, 36, is twice Demi's age—quick math—aaaaand she's 18. Perez Hilton and E! News say that things have gotten pretty hot and heavy between the two recently, but that the relationship kind of started cooling down after Ryan's ex-girlfriend gave birth to his baby girl, Kai. Nothing like a little baby-mama drama to hopefully scare an 18-year-old girl into being a single teen again.

We wonder what 18-year-old Demi Lovato's parents think about the recent rumor the young singer has been hooking up with the much older actor (and father) Ryan Phillippe, 36? According to E! News, the two have been secretly seeing each other for a couple of months now. A source claims Lovato and Phillippe started dating each other casually at first, but things got hot and heavy pretty fast.

Disney princess Demi Lovato, rebounding with former That '70s Show actor Wilmer Valderrama? Don't believe the hype. In one of the more bizarre rumors to emerge since Lovato, 18, entered rehab last week to be treated for "emotional and physical" issues, the New York Post reported that Lovato began dating Valderrama, 30, after her breakup with Joe Jonas earlier this year. Unfortunately, as enticing as this celeb-dating tidbit might be, it seems to have no basis in reality.

It's pretty clear that being a Disney star has its ups. It's like a gateway to instant fame. Not to mention being surrounded by other attractive, amazing talents... And when love blooms between co-stars and friends, it's hard to imagine that anything can go wrong when you have it all. But then when you take Demi Lovato, the latest Disney star who's just checked herself into rehab for "emotional and physical issues," according to US Magazine, you have to wonder how much you can take when stardom and a fairy-tale like romance flip upside down in a matter of months.

Kevin Jonas gave his family another reason to celebrate this month, marrying his girlfriend, Danielle Deleasa, in New York on Saturday.

Miley Cyrus's heart is on her sleeve with a crush on Robert Pattinson and hurt feelings from her ex. YourTango's Celebrity Love has the details.

It looks like Demi Lovato and Trace Cyrus' romance is over before it even had a chance to bloom off-line. The two musicians have been keeping up a heavy stream of twitter flirts since May while Trace was on tour with Metro Station, but according to Hollywood Crush have quickly come to see the error of their ways.
