It isn't every day that a man gushes over his future father-in-law's incredible abs. But the admiration is understandable when that future father-in-law is rocker Lenny Kravitz.

Channing Tatum heaped praise on Lenny's 6-pack abs in an Instagram post on Wednesday.

Channing, 41, couldn't help but admire the 57-year-old rocker's washboard abs after he shared a photo on the social media platform.

The "Magic Mike" actor, who is reportedly in a relationship with Lenny's daughter Zoe Kravitz, 32, commented:

"Good god man! What are you eating or what's in the water or the genes. It's not natural. Do you just do abs like all day?"

In response, Lenny joked that he wants a role in the next "Magic Mike" film, referencing Channing's 2012 film about male strippers.

The studly musician replied: "Dude, I'm just trying to get in the next Magic Mike. Any connections?"

Channing, who is rumored to be bisexual, first sparked dating rumors when he and Zoe were spotted on a bike ride in New York City last month.

They were seen leaving the Met Gala hand-in-hand earlier this month.
