A decidedly huge list of celebrity guest stars was milling about, including Pharrell Williams, Spencer Pratt from “The Hills,” Cobra Starship’s Gabe Saporta and Ryland Blackington, and former Blink-182 singer Mark Hoppus. So, really, what is going on here? Wentz then added that, yes, there’s going to be plenty of cameos in the video, only they’ll all be done with a decidedly “Tom Cruise-ian” twist. And that sort of explained another scene we witnessed, one that showed Pharrell ripping off what appeared to be a Stump mask and then singing along with the track. “We’re all fans of ‘Mission Impossible,’ and in part three, they really nailed it, where they had these great masks with these great reveals,” Wentz said. “So me and Pharrell and Spencer and Gabe and Mark Hoppus all went and got our faces cast, like plaster castings made, and we’re going to do actual reveals. So I hope they look good. … I hope I’m not putting my foot in my mouth or anything right now.”
