Mark-Paul Gosselaar has had his dark brown beard for quite a while now -- for months, in fact, ever since he started filming and promoting his new show, Pitch -- but Monday night was the first time we audibly gasped at it.
It's like a whole different person. We're not gonna lie, though -- we kind of dig it. It's like he's… saved by the beard. (Get it? Right, yes, we're burying out heads under a blanket now…)
Now that we're all staring, let's take a journey through the life of MPG's main mane.
In January, when Gosselaar and McGinn brought their sons, Michael and Dekker, to the Monster Energy Supercross Celebrity Night at Angel Stadium of Anaheim, we still had no idea what we were in for. But, oh, the foreshadowing:
The first hints of legit facial hair then went golfing in February:
ET's Sophie Schillaci caught up with the California native at the Men's Fitness event, where he didn’t talk about the facial hair he grew for the show, but he did talk about his insanely strict new diet regimen for it called ketogenic.
"It's basically paleo, but even worse -- or better, depending on how you look at it," he explained. "It's pretty hard, especially for us, because we're so active. We're doing this whole baseball thing. We're training sometimes three hours a day. Unbelievably [with] keto, you don't do any carbs. It's all animal proteins and fats and vegetables and things that have low carbs and no starches. You have energy. Your body is pumping out the fat."
Though it's tough to stick with such a strict diet, he said that his "wife is a saint," and helps him maintain his proper food intake.
"She cooks meals for me, for the kids, for herself, and we have cheat days every once in a while," he admitted.
His favorite cheat day meal? "Pizza and ice cream," he said.
