Wilmer Valderrama posted a message on Twitter to wish girlfriend Demi Lovato a happy birthday in a rare public display of affection.

The That 70’s Show actor has always been private about his romantic involvement with the Unbroken singer.

But Wilmer broke his silence to share a sweet picture of the pair together on Demi’s 22nd birthday.

The shot shows Wilmer and Demi wearing matching festive tops, looking at each other and laughing.

“Wishing you happy birthday would never come close to all the inspiring things I wish for your life," Wilmer captioned the shot.

"We laugh our a**es off. While we do all we can to better everything around us.. Love you through all."

Wilmer’s message comes after Demi previously wished him a happy birthday on his big day back in January. Calling him "the funniest, most inspiring, incredible man I know”, Demi added: “You truly are a light to this world and to my life."

Wilmer and Demi celebrated her birthday by spending the day together on Wednesday at Disneyland, California.

Former Disney starlet Demi and actor Wilmer, 34, first started dating back in 2010. They then split in 2011 before rekindling their relationship later that year. They are believed to have been together ever since.

Speaking in February 2013, Demi, who previously suffered from depression, said she was happier than ever in her personal life.

"I'm in a place where I can finally trust and love and be a better person for the man I am in a relationship with, instead of being a clingy girlfriend or getting jealous," she told Cosmopolitan Campus magazine.

"It is very unhealthy when girls devote all of their time to a guy and forget their friends and family. I did that. I was always looking for distractions because I was so afraid of being alone."
