Norman’s Rising Stock On ‘Walking Dead’ Has Gone To His Head: ‘His Attitude Stinks!’

Norman Reedus is alienating his Walking Dead co-stars, who say he’s gotten way too big for his boots lately, RadarOnline.com has learned.

“Norman has always been a fan favorite on the show,” an insider told RadarOnline.com. “But things have clearly changed now that he's made a new long-term deal and will be the sole series leading man by end of the season.”

As RadarOnline.com readers know, show star Andrew Lincoln, who plays sheriff Rick Grimes, has left the AMC thriller, meaning Reedus, 49, takes over the top spot on the call sheet. And that new designation has apparently already gone to his head.

“He rolls with a much bigger entourage and is putting more distance between himself and the other cast members,” the insider revealed. “He also insists on being introduced last, and with a lot of fanfare, when the cast gathers for promotional appearances like they did at Comic Con.”

Being the top dog is what Reedus, who just welcomed a baby daughter into the world with girlfriend Diane Kruger, has long wanted. But along with the added payday and pampering comes more scrutiny from his castmates and friends.
