The stars play a couple on the U.S. Tv drama, and editors at Us Weekly's gossip website reported on Friday (05Jul13) that romance has been blooming for them offscreen as well.
The couple was said to have been dating since April (13), but the 23-year-old blonde beauty has now taken to her Twitter.com page to set the record straight.
She writes, "Haha Us Weekly what are you gonna come up with next??? Hilarious. Although I do love you tyler."
Benson and Blackburn first sparked speculation of an offscreen relationship when they were spotted holding hands and cuddling up to one another at the Coachella music festival in California in April (13).
The hunk will soon leave Pretty Little Liars to star in its spin-off Ravenswood.
