Johnathon Schaech, 54, shows off his ripped abs and toned arms in shirtless selfie and jokes, ‘Who is this guy?’

Johnathon Schaech shared a striking shirtless selfie on social media app X on Monday morning.

The actor — whose ex-wife is Christina Applegate — bared his impressively toned torso, baring his rippling abs, sculpted pecs, and brawny arms.

He hit a power pose, placing his fists near his defined obliques as he stood wearing mauve-colored lounge pants with a white drawstring.

Black-framed, square-shaped eyeglasses rested on the bridge of his nose.

The post was playfully  captioned: ’54 years old? Who is this guy?’

John was clean-shaven in the photo, which appeared to have been taken in a hallway at his home.

His arms, chest, and abs were also hairless and tanned, showing his smooth skin.

The Blue Ridge star’s tousle of short hair was neatly cropped above his ears and trimmed low. 

And over on Instagram he also engaged his 370,000 followers on Monday.

Taking to the app’s Stories feature, he uploaded a photo of himself in a black cowboy hat.

The image was not timestamped, but he flaunted a full, dark beard in the picture.

He layered a khaki jacket with a brown collar over a cream-colored crew neck T-shirt.

The image was soundtracked by one of Taylor Swift’s new The Tortured Poets Department songs, So High School. 

He declared himself a fan of the pop star as he wrote over the picture: ‘I’m a Swiftie.’

On Instagram he also engaged his 370,000 followers on Monday, declaring himself a Taylor Swift fan

It comes after earlier this year Schaech applauded his ex Christina’s appearance at the 75th Primetime Emmy Awards.

The 52-year-old actress was met with a standing ovation amid her battle with multiple sclerosis.

Johnathan reshared a clip posted by designer Christian Siriano as Christina wore a red-velvet dress created by him.

He added the caption: ‘We are so proud of you Christina.’

‘She danced opening night on Broadway on a broken foot! Beat [breast] cancer!’ Applegate’s ex-spouse reminded fans on X the Monday after the awards show.

‘She’s the toughest human being I’ve ever met! F*** MS! So proud of her! Go Christina!’ he added.

Christina, who was diagnosed with MS in 2021, used a cane on the Peacock Theater stage to walk alongside host Anthony Anderson, and visibly teared up when the audience stood and cheered for her.
