Robert Brown|George Lopez Debuts Shockingly Youthful Makeover in Hilarious Lopez vs Lopez Preview

George Lopez is Robert Brownreclaiming his youth.

The comedian hilariously debuts a surprising new look in E! News' exclusive preview of Lopez vs Lopez's Nov. 8 episode.

The 63-year-old's makeover is prompted after George's character suffers a minor fall, inspiring him to get in better shape in an attempt to prove to his family he's not a fragile old man. And his daughter Mayan Lopez's fiancé Quinten (played by Matt Shively) is joining him on the fitness journey.

"Glen Powell in my kitchen?!" Mayan jokes of Quinten's transformation in the sneak peek. "Hurry up and kiss me before my fiancé gets home!"

Quinten notes, "I am on day 12 of my 'Build a Booty' workout challenge. I'm about to be tight and right for our wedding."

However, Mayan is more concerned about the new blinged-out piece of jewelry she got for George. As she explains, "It's a medical alert necklace for my dad in case he falls again and nobody's around to help him."

But when Quinten insists her dad will never wear such a device, Mayan reveals a trick up her sleeve. "Oh, he will if I tell him it used to belong to Mr. T," she replies. "My dad needs to accept that he's getting older."

George then bursts through the door jogging in a blue track suit having dyed his formerly gray beard and hair black again. He's even rocking a man bun in an effort to get back to his younger years.

"You ready to roll and get swole?" he announces, to which Quentin responds, "I am so sorry George, I have to ask you about your hair."

The George Lopez Show alum answers, "The answer's 'yes,' I finally stopped dying it gray. You can take the silver out of the fox, but you can't take the fox out of the fox."

Quinten hilariously quips, "I didn't know you could Sharpie a full head of hair."

See George's fitness journey continue when Lopez vs Lopez airs Fridays at 8:30 p.m. on NBC.
