Agassi got violent as I licked Matt LeBlanc

Brooke Shields made a career-changing cameo in a 1996 episode of “Friends” — but it propelled her then-husband Andre Agassi into a violent, destructive fit of rage.

In “The One After the Super Bowl” episode of the classic NBC sitcom, a hilarious Shields stole scenes as soap star Joey Tribbiani’s (Matt LeBlanc) finger-licking stalker, Erika.

Alas, tennis legend Agassi, an eight-time major champion and an Olympic gold medalist, wasn’t laughing.

After one scene showed the LeBlanc and Shields getting a little too intimate — yes, the “Pretty Baby” icon tongued his digits — the seething racket champ stormed out of the studio audience.

The “Blue Lagoon” icon was scripted and directed to lick LeBlanc’s fingers “because they’re the hands of a [surgical] genius … and I [wanted] to devour them, and I’m a nut,” she told told the New Yorker in new interview.

“[Agassi] said, ‘Everybody’s making fun of me. You made a fool of me by that behavior,’” Shields, 57, recalled. “I’m, like, ‘It’s comedy! What is the matter with you?’”

The actress and author later learned that Agassi, 52, was abusing crystal meth at the time.

“So that irrational behavior I’m sure had something to do with that,” she said. However, as soon as the pair got home, Agassi “smashed all his trophies.”

The Post has reached out to Agassi’s reps for comment.

Meanwhile, the mother of two also revealed that she thought LeBlanc, 55, was “cute” at the time of the shoot: “He was, like, ‘I’ve washed my hands and they’re all clean.’ I was, like, ‘I had a mint!’”

Her comedic role on “Friends” was such a hit it led to her scoring her own NBC sitcom, “Suddenly Susan,” which ran from 1996 to 2000.

Shields and Agassi remained married from 1997 until 1999, and Shields wedded current husband filmmaker Chris Henchy, 59, in 2001.

Earlier this month, Shields — who is currently promoting her acclaimed Sundance doc “Pretty Baby,” premiering April 3 on Hulu — got candid about sexual abuse she suffered in her 20s by a Hollywood executive.

She said it’s taken her a “long time to process” the incident that occurred in 1987 following her graduation from Princeton University.

Shields first revealed the post-college assault in her Hulu documentary, “Pretty Baby” that was released this past January.

“I’m more angry now than I was able to be then,” she said. “If you’re afraid, you’re rightfully so. They are scary situations. They don’t have to be violent to be scary.”

She met the anonymous exec for dinner and she initially believed that it would lead her to receiving a film role after an her extended hiatus to attend college.

Once the evening concluded, she went back to his hotel to call a cab. When they got there, the man began “wrestling” on top of her.

“I didn’t fight that much,” Shields said. “I didn’t. I just absolutely froze. I thought one ‘No’ should’ve been enough, and I just thought, ‘Stay alive and get out,’ and I just shut it out.”

“Sometimes I’m amazed I survived any of it.”
