Norman Reedus Instagrams ‘The Walking Dead’ Season 5 Poster Featuring Rick Grimes With A Twist

Norman Reedus wished his buddy from "The Walking Dead" Andrew Lincoln, who turned 41 on Sept. 14, by posting "The Walking Dead" Season 5 poster featuring the birthday man. However, the photo shared by Reedus is quite different.

In the photo, Andrew Lincoln, who portrays Rick Grimes in the show, is crouching and "Pooping" is scribbled on it. Check out the photo, here.

"Happy birthday to one of the best people I know," Reedus captioned the photo.

Norman Reedus (who plays Daryl Dixon) and Andrew Lincoln are great friends. It will be interesting to know how Lincoln will respond to this.

Lincoln was born in London on Sept. 14, 1973. The actor's real name is Andrew James Clutterbuck and Lincoln is his stage name.

He started working for AMC's "The Walking Dead" in 2010 and his character transformed from the pale-looking sheriff's deputy to a fierce and brutal man who can kill anyone if they harm his family.

The actor appears on the cover of "Men's Fitness" magazine's Oct. 2014 issue. He also talked to the magazine about his fitness and training for shooting challenging sequences.

"I made a conscious effort to train and build up a little bit, and for the first time in my life got a personal trainer. It was the first time I went on a diet. We would do repetitive weights until failure, and there's a sick part of me that really dug it," Lincoln said.

He revealed that he was more into running than hitting the gym, however his trainer asked him to cut down his running and gain some mass for the role. He ditched sugar and carbs and included free weights.

Steven Yeun (Glenn Rhee) also talked about Lincoln giving his all and pushing it harder.

"But no, there's Andy, and he's showing up and pushing it harder than anything. He's the culture of the show. I mean, if your No. 1 guy isn't a diva, then who can be.?" Yeun said to Men's Fitness.

"The Walking Dead" Season 5 airs Sunday, Oct. 12, 2014 on AMC.
