Hayden Panettiere: 'Having A Blast' with Scream 4!

Hayden Panettiere and Emma Roberts share a laugh as they take a break from filming Scream 4 on Tuesday (July 20) in Detroit, Mich.

The 20-year-old actress and her 19-year-old co-star both wore warm fleece lined boots while hanging out on set!

“For an audience that is so well-versed in Scream [films] and in what happens and who becomes the killer, it’s trickier to throw them a curveball,” Hayden told MTV. “I think they’ve done a really cool job with the script, [and] we’ve had a blast on it.”
