Vanessa Hudgens says all is good between her and Zac Efron, despite their recent break-up.

But the actress might not be feeling so chipper today, considering a new report from E! News that links her ex to his most recent co-star: An on-set source says Efron and The Lucky One actress Taylor Schilling are acting "chummy" these days.

Yes, chummy.

"They joke around, eat together sometimes, run lines," the insider says, though he/she is quick to point out the relationship so far is "nothing out of the ordinary."

Efron and Schilling are filming this romantic movie in New Orleans, joining Miley Cyrus and the Twilight crew as major stars taking over The Big Easy. Aside from providing serious eye candy for all residents, this also means paparazzi will be swarming the bayou all winter.

If anything does go down between Zac and Taylor, it will be difficult to hide.
