Los Angeles, Feb 7: Is Zac Efron dating Lily Collins? They have been seen together at a restaurant here.

The Hollywood pair was spotted sneaking out of the back-door of the STK Steakhouse Saturday night after enjoying a meal together.

Efron, 24, was seen hopping into a chauffeur driven SUV, closely followed by the 22-year-old actress, reports femalefirst.co.uk.

"Zac literally ran to the car and jumped in, leaving Lily behind. But Lily kept her cool and took her time. She wasn't as worried about not being seen by us. She probably didn't want to trip in her heels," a photographer told x17online.com.
