Zac Efron, Taylor Schilling getting ``chummy`` on new film’s set

New York: Zac Efron has reportedly been spending a lot of time with his co-star Taylor Schilling.

The two are shooting for their new film ‘The Lucky One’ in New Orleans.

Rumours of a romance began this week after Star magazine reported that newly single Efron had "instant chemistry" with the 26-year-old Schilling.

But, according to E! Online, the actors’ bond hasn’t turned romantic – yet – though they have gotten "chummy."

"They joke around, eat together sometimes, run lines. Nothing out of the ordinary," the New York Daily News quoted a source from the set assaying.
