Zac Efron, Lily Collins Spotted Hanging Out Together

Is Zac Efron dating Taylor Lautner's ex-girlfriend?

According to X17online.com, Efron, 24, was spotted hanging out with "Mirror Mirror" actress Lily Collins, 22, Saturday night. The pair reportedly grabbed dinner in L.A. at STK steakhouse and left together in the same chauffeured car.

Collins, daughter of British musician Phil Collins, was last linked to "Twilight Saga" stud and her "Abduction" co-star Taylor Lautner. However, the couple reportedly called it quits in September.

In the March 2012 issue of Seventeen, Collins talks about some of her past celebrity crushes.

"It's weird to have celebrity crushes now because I could actually meet them or work with them!" she said. "When I was younger, it was definitely Leonardo DiCaprio in 'Titanic.' I had pictures of him and ... I had the biggest crush on Justin Timberlake!"

Could Efron and Collins be more than just friends? It looks like we'll just have to wait and see, but we wonder if she ever had any "High School Musical" posters on her wall growing up.
