Ladies and gentlemen, we present... Cofron?
Onlookers spotted Zac Efron and Lily Collins dining together at Los Angeles eatery STK on Saturday, with one witness telling People they arrived together "holding hands."
On the scene for a birthday party in honor of one of Zac's friends, Efron and Collins "had a drink at the bar together and then joined the birthday crew on the patio," the insider adds, while sources say the actor then continued his evening at Lexington Social House.
Efron most famously dated Vanessa Hudgens for many years, while Collins was linked to Abduction co-star Taylor Lautner throughout most of 2011. She'll next be seen opposite Julia Roberts in Mirror Mirror.
