"Happy Birthday @ninadobrev !!! The world loves you!" wrote the hunky actor, 35, on Twitter. "We all do;) Enjoy the moment, enjoy the day,enjoy the year!" he tweeted.

Somerhalder and Dobrev were real life lovers until May last year. The two split up but continue to remain good friends. The duo are also a reel-life couple in Vampire Diaries for which they won an award for "Best Onscreen Chemistry" at the 2014 People's Choice Awards held January 8, 2014.

Amidst rumors that the two may be reuniting soon, Somerhalder and Dobrev were bold enough to joke about their relationship on stage while receiving the award.

"We started dating on the show," Dobrev, 25, said. "We started dating in real life," added Somerhalder.

"Then we broke up in real life," the Canadian actress said. "And yet our characters are still dating on the show," joked Somerhalder, finishing her sentence.

When asked by a reporter at the Award event whether he and Dobrev have resumed dating each other, the actor refused to reply, instead giving the reporter his trademark sexy, lopsided smile.

Dobrev, on the other hand got tongues wagging when she made an appearance at the event hand-in-hand with a "mystery man," EntertainmentWise.com reported. The man has not been identified yet.
