Nick Cannon thinks 50 Cent should be in da gym instead of “In Da Club.”

The actor made the comments about the rapper’s physique during Friday’s episode of his “Daily Cannon” podcast while discussing 50 Cent’s ex-girlfriend Vivica Fox, whom the rapper split from in 2003.

“You can like, fantasize about Fif from 15 years ago,” Cannon said on the episode, adding that the rapper, whose real name is Curtis Jackson, is now “different” and “fat.”

“He look like he got a pack of hot dogs on the back of his neck,” the comedian added.

Cannon’s co-hosts Mason Moussette and Courtney Bee disagreed, arguing that they still find 50 Cent attractive.

“You looking at them pictures from ‘Get Rich or Die Tryin’,’ now it’s get thick or die fryin’,” “The Masked Singer” host quipped.

50 Cent hasn’t yet publicly responded to Cannon’s podcast critique.

The Post has reached out to reps for 50 Cent and Cannon for comment.

Cannon posted a clip from the podcast to Instagram, where users called him out for his remarks.

“Nick, I rate you and all but man, but you need to stop… lol, 50 cent ain’t never coming on any show you on, you know this,” one user wrote.

“Nick [you’re] barking up the wrong tree lol! Leave that dude alone,” agreed another.

Some thought 42-year-old Cannon may have been a bit envious of the 47-year-old rapper, suggesting he was mad because 50 Cent roasted him in 2019 over a diss track Cannon wrote aimed at Eminem.

In 2019, 50 Cent called Cannon’s diss track “trash” in a now-deleted Instagram post, saying he couldn’t understand why Cannon would pick a fight with Eminem, who he described as a “different kinda animal.”

“I haven’t seen a motherf – – ker come close to beating him man,” 50 Cent wrote in the post, according to Revolt. “Hey Nick that s – – t was trash, I oughta kick you in yo ass when I see you PUNK!”
