Taylor Swift and Zac Efron enjoy flirty dinner date

Washington: Taylor Swift and Zac Efron were spotted having a flirty dinner at L.A. Italian eatery.

On Jan. 6, the ‘New Year’s Eve’ hunk shared an outdoor corner table with the country superstar at Pace. According to a fellow diner, the pair arrived together in Efron’s Audi.

“(They) were deep in conversation and very giggly,” a magazine quoted a fellow diner as saying.

It’s not the first time the cute duo has flirted in public. Back in 2009, Efron – who is single since splitting with Vanessa Hudgens in December 2010 – called Swift a “lovely girl, very beautiful.”

In turn, the Grammy-winning singer, dumped by Jake Gyllenhaal in December 2010, gushed that Efron was an “all-around amazing guy.”

However, one Swift insider insists, “They were in L.A. doing press stuff together, and after they were done, they decided to grab dinner.”

They’re costars in the film ‘Dr. Seuss’ The Lorax’. And an Efron source said, “They have been friends a long time.”

But another insider ruled out the possibility of their being romantically linked as “they are on totally different wavelengths.”

“Taylor thinks Zac’s cute…[but] they are on totally different wavelengths,” the source added.
