Jesse Watters and the panel on "The Five" discussed attorney Michael Avenatti's reported offer to battle Donald Trump Jr. in a "three-round mixed-martial arts fight."

Avenatti replied to a tweet by MSNBC media reporter Dylan Byers, who said he was eating lunch with Avenatti when the topic was breached.

"I'm having lunch with Michael Avenatti at the Vanity Fair Summit and he’s proposing a three-round mixed-martial arts fight with Donald Trump Jr. for charity. No joke," Byers tweeted.

Avenatti retweeted the message, adding that "this would be for two great causes, I'm in."

Avenatti said that he would donate his share of the proceeds to "rebuilding Puerto Rico" and to the anti-sexual assault organization RAINN.

"I think Junior would knock him out," Jesse Watters said in response to the tweets.

Greg Gutfeld added that Avenatti will "do anything to stay in the spotlight."

Earlier this week, Trump Jr. invoked Avenatti in a tweet, asking his followers if they would support a Democratic presidential ticket in 2020 featuring Avenatti and disgraced Brooklyn, N.Y. Congressman Anthony Weiner.

Avenatti has said he is considering a bid in 2020.

Trump Jr. joked that such a ticket would be "Carlos Dangerous" -- in reference to an alias once used by Weiner.

Avenatti blasted Trump Jr. in response to the remark, calling him "Bif" -- in an apparent reference to bully Biff Tannen from "Back to the Future."
