Andrew Lincoln may be the star of arguably the biggest show on TV now, but he hasn't watched a single episode of the hit series.

"I don't watch the show. I don't need to. I get to live it everyday," said the 40-year-old English actor who plays sheriff Rick Grimes on AMC’s The Walking Dead, based on a graphic novel where zombies (or "Walkers") have over-run the earth. The show, currently in its fourth season, has become a global phenomenon, sparking renewed interest in zombies and the undead the world over.

Asked to elaborate further, Lincoln -- who is currently on a three-day stopover in Singapore to promote the show along with fellow star Norman Reedus -- said he became self-conscious after watching himself in previous TV shows he'd done.

"I just don't watch myself. I wouldn't like this or that. It wasn't helpful to me and since then, I stopped watching myself", he said, who added that he would never direct an episode of the hit show if offered the chance for the exact same reason.

In fact, during a two-hour meet-the-fan session held at the LaSALLE College of the Arts in town, Lincoln covered his face and ears when two clips of the show were aired.

His frank confession was among precious tidbits of the show -- currently on a mid-season break of its fourth season -- fans and student actors were treated to as Lincoln and the irreverent Reedus held court.

Among other gems -- actors are not allowed to keep any TV scripts for fear extras would steal or lift them out of the bin and leak spoilers to the publics for fear and that the show, currently on a mid-season fourth season break, would be back with a bang next month.

"There are three episodes in the second half of this season that are the best we've ever done. You see the prison family at their most vulnerable and they are slowly breaking down on their own, " said Lincoln, who labelled the TV series a "family drama set in hell".

"Long may I survive. I could be dead already," he cheekily added, in reference to the show's notorious reputation for killing off key characters at a moment's notice.

Meanwhile, the playful Reedus -- with whom Lincoln shared an obvious and deep camaraderie -- delighted the fans by not sitting still.

"I saw a Walking Dead porno the other day. I can show you when we get back to filming," he said, playfully looking at Lincoln.

Earlier on, Lincoln and the "incorrigible" Reedus seemed to be genuinely taken aback by the hundreds of mostly teen and young adult fans who had gathered at LaSalle to meet the stars. But they quickly got over their surprise and won them over by posing gamely for "selfies" with the fans.

"It's crazy. We live in a bubble because the show is shot in the middle of nowhere. And then we come here and get assaulted," Lincoln said to laughs.
