George Lopez shocked fans with his disheveled appearance as he stopped by The Jennifer Hudson Show on Thursday.

The comedian, 63, showed off some of his dance moves in a lighthearted clip that was filmed backstage ahead of taping the episode.

The actor – who was heckled by a crowd amid a stand-up show last year – sported long gray hair as well as a scruffy beard in the video which was uploaded to the show’s account on X.

Lopez wore a dark navy suit and strutted down a hallway while surrounded by staff members who sang a tune to the theme song of his sitcom George Lopez, which aired from 2002 through 2007.

‘Oh my gosh! George is at the happy place now!’ they could be heard singing. At the end of the reel, the star blew a kiss and expressed, ‘I love you so much, thank you!’

However, social media users were more focused on his altered look rather than the song, with one penning, ‘What happened to dude. He was normal looking 5 years ago.’

‘Someone said “I’ll bet you can’t be Mexican and look like Karl Marx.” And George said “hold my beer,”‘ another wrote.

Last year in October, he also briefly opened up about the Prime Video special being his last on the Tamron Hall Show.  

‘It is the last one. I’ve subjected the American people to enough of my crap,’ he said on the show. 

‘It seems like the right time; it’s been the one thing that has just never left me my whole life and it’s a wonderful place to leave it at this particular point.’ 

Aside from the upcoming special, George has also been starring in the sitcom Lopez vs. Lopez which aired its third season last fall.
