Seems like more love is in the air on the set of 'The Vampire Diaries,' but this time around it's between recently divorced actor Paul Wesley and his former costar on the show, Phoebe Tonkin.

The new couple was spotted out getting hot and heavy on what appeared to be a date over the weekend (Sept. 21).

"[They were] on a double date with Ben McKenzie and Shelley Hennig," an eyewitness told Us Weekly of the evening they spied on. "It looked like Paul and Phoebe might have set Ben up with Shelley -- seemed like a first date."

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

Wesley split from his 'Pretty Little Liars' star and wife, Torrey DeVitto, two months ago after a two-year marriage. Tonkin, on the other hand, will be rejoining the vampire cast in its brand new spin-off series, 'The Originals.'
