Isla Fisher is keeping it real.

The Australian actress, 50, recently appeared on “The Smallzy Show” with her “Spa Weekend” co-star Adam Demos and broke down her icks with leading men on screen that could turn off female audience members.

“When a man runs on film, and it looks like a sprinkler moving, it’s just wrong,” Fisher said on the Australian radio program. “Tom Cruise has really nailed the sexy run.”

An ick is a sudden feeling of disgust. It is popularly used online when describing feelings of repulsion that suddenly crop up with a romantic partner.

Fisher also shared her thoughts on wearing backpacks: “If a bloke shows up in a backpack, wrap it up. It’s done.”

“It’s like you can wear a backpack, but if you click your backpack together … it’s not good,” she continued. “It’s like if you wear a hoodie, but you zip it all the way up, it’s not good.”

Fisher reveals ultimate ick

Fisher is among the cast of the new movie “Spa Weekend,” which also stars Anna Faris, Michelle Buteau and Leslie Mann.

The movie, set to be released in theaters on Friday, Aug. 21, follows a group of childhood friends who book a few days at a resort to relax when Fisher’s character Mel shows up, crashes the weekend, and gets them in trouble with the spa’s owner.

While on “The Smallzy Show,” Fisher revealed her ultimate ick. She recalled a man she saw wearing boat shoes.

“He slipped the heel off, and he was wearing it like a plimsoll,” she joked. “I could see his heel. Repulsive.”

Fisher opens up about life post-divorce

Fisher opened up about pouring herself into her friendships post-divorce in an interview with People. The actress and her ex-husband, “Borat” star Sacha Baron Cohen, announced their split two years ago.

“I’m divorced, so all I do is see friends!” Fisher joked, adding that her children “are my friends in my life. So I’m in a different place.”

Fisher and Cohen met at a party in Australia in 2002 and married in 2010 in Paris. The pair have three children, two girls and a son, the youngest born in 2015. They reportedly made their divorce official last June.

Fisher told the outlet that her friends are used to her busy schedule and “understand how it goes.” However, she said she has a handle on work-life balance: “I feel really grateful to be working. I feel really grateful to be a woman of my age in the business. And I’m really happy to be in a movie like this.
