Demi Lovato thinks her boyfriend is “perfect”.

The Skyscraper singer has been dating Wilmer Valderrama since 2010 but they keep their relationship relatively private and only acknowledged it earlier this year. However the 22-year-old couldn’t resist sharing a photograph of the actor kissing her on her cheek.

“I never post personal pictures like this but f**k.. He is perfect. I miss my @WValderrama,” she wrote on Twitter. In the shot, both are dressed down and Demi looks fresh faced with a big smile on her face. It helps the star clear up any rumours about them being on the verge of a breakup. Earlier this year Wilmer's social media account was hacked and raunchy private images of Demi were leaked. Not long afterwards there was speculation that the pair had called it quits, but that is apparently not the case.

"Demi and Wilmer are not broken up," an insider told RadarOnline.com. "They are still a couple and very much in love."

The former X Factor USA judge seems to be currently separated from her 34-year-old beau as she tweeted earlier in the day about her movements in Amsterdam, Holland. She took time out from her busy schedule to take in the sights and one in particular had a profound effect on her.

“Can't stop thinking about Anne Frank and her story after visiting the Anne Frank museum today,” she wrote. “What a precious, brave and beautiful soul...”

Before meeting the That ‘70s Show star, Demi dated Miley Cyrus’ older half-brother Trace Cyrus in 2009 and dated her Camp Rock co-star Joe Jonas in 2010. She remains close to the latter’s brother, Nick, and the pair recently paired up to duet on the song Avalanche.
