There sure are some heavy-hitting star cameos in “Scary Movie 5.” Sources said Mike Tyson was on the Atlanta set yesterday with Heather Locklear. We’ve reported that also appearing in the Dimension Films flick are Lindsay Lohan and Charlie Sheen, who shot a scene together in bed, as well as “Mob Wives” star Angela “Big Ang” Raiola and “Real Housewife of Atlanta” Sherée Whitfield, who producers say “go to blows in an unforgettable fight scene.”
