"The Vampire Diaries" season 5 seems to be heating up prior to its premiere date with its cast having off-screen romances. Just days after the rumor mill began swirling about Nina Dobrev dating Derek Hough following her break up with Ian Somerhalder, reports surfaced that Phoebe Tonkin and Paul Wesley are dating.

The actor recently divorced from his wife, "Pretty Little Liars" actress Torey DeVitto, and it seems like the vampire hunk is already moving on with a new lady.

It was revealed that Wesley was spotted getting cozy with his former co-star. According to Us Weekly, Tonkin and Wesley were not shy about hiding their affection for each other on Saturday night while out at Soho House.

A source told the magazine, "[They were] on a double date with Ben McKenzie and Shelley Hennig."

The eyewitness added, "It looked like Paul and Phoebe might have set Ben up with Shelley -- seemed like a first date." The actress even posted a picture on her Instagram account about her New York trip.

Wesley and McKenzie are coincidentally best friends, the two were recently spotted in Las Vegas where they celebrated the former "O.C." star's 35th birthday on Saturday, September 14th.

The source alleged that "Paul and Phoebe were 100% romantic - they were across the table from Ben all cozied up on the couch kissing each other, adding that "she had her head on his chest."

The news of the 31-year-old romancing the 24-year-old brunette comes after his spilt from DeVitto, 29, in July and Tonkin's split from her former "The Secret Circe" co-star Chris Zylka.

The reps for the Wesley and DeVitto confirmed their split to the magazine. The statement confirmed that the two "have decided to amicably split."

However, the statement said, "They will continue to remain good friends." The former couple met in 2007 and tied the knot in a private New York City ceremony in April 2011

"The Originals" is set to premiere October 3rd.
