Bulgarian-born Hollywood actress Nina Dobrev celebrates her 23rd birthday on Monday.

Meanwhile, rumors have continued circulating that Dobrev and Vampire Diaries co-star Ian Somerhalder may be about to get married.

According to London Free Press, the couple, who looked "positively glowing" when they got back to work last week, have fueled the rumors with "mysterious" tweets.

The pair spent the Christmas on a ski trip, allegedly in Canada. "I'm on top of the world!", Nina Dobrev tweeted on December 26, while Somerhalder wrote "Good-bye mountain paradise" on the last day of the trip, adding "A new paradise I am headed."

In this week's brand new episode of The Vampire Diaries, Elena and company will help Caroline cheer up for her 18th birthday, TV Fanatic has reminded.
