Taylor Swift and Zac Efron have enjoyed a flirty dinner date. The "Safe and Sound" hitmaker and the New Year's Eve star - who have been friends for years - were spotted sharing a romantic corner table at Los Angeles restaurant place earlier this month.

A source said that the couple - who arrived together in Zac's Audi - "were deep in conversation and very giggly." However, friends of Zac, 24, and 22-year-old Taylor claimed the Lorax co-stars were just enjoying a friendly night out.

"They were in L.A. doing press stuff together, and after they were done, they decided to grab dinner," one friend said.

Another friend added, "They have been friends a long time. Taylor thinks Zac's cute...[but] they are on totally different wavelengths."
