Rebecca De Mornay is still fond of Tom Cruise more than 40 years after appearing with him in “Risky Business.”

The actress, 65, praised her former co-star during an exclusive interview with Page Six published Saturday, July 19.

“I’m really proud of him,” De Mornay said while promoting her new “Saint Claire” thriller. “I’m really, really proud of him.”

“Risky Business,” which was both De Mornay and Cruise’s breakout film, was released in 1983.

The coming-of-age teen comedy sees high schooler Joel Goodsen (Cruise) fall for prostitute Lana (De Mornay) while his parents are away on vacation.

After first meeting on the set of the classic movie in 1982, De Mornay and the “Mission: Impossible” star dated in real life for nearly three years.

De Mornay now likens Cruise, 63, to a “major chord,” whereas she is a “minor chord.”

“He’s like, ‘I am Top Gun and that’s what America really wanted,’ and so he’s fulfilled it,” she explained. “He is a brilliant, brilliant interpreter of what the zeitgeist is.”

“I’m really, really proud of knowing him from when we were in the suburbs of Chicago and knowing what he wanted and where it is now,” the actress added. “We started this together, and look what he did with it.”

Following the success of “Risky Business,” Cruise went on to star in not just the blockbuster “Mission: Impossible” and “Top Gun” franchises but also hit films like “A Few Good Men,” “Jerry Maguire” and “Eyes Wide Shut.”

As for De Mornay, she has appeared in “The Hand That Rocks the Cradle” and “The Slugger’s Wife.”

“Saint Claire,” the actress’ latest movie that also stars Bella Thorne and Ryan Phillippe, is perhaps De Mornay’s grittiest project yet.

Thorne portrays a serial killer who murders misbehaving men, and De Mornay admitted that the script impressed her.

“It’s very rare that I read scripts about a female serial killer who’s obsessed with Joan of Arc, which I thought was just brilliant,” she told Page Six. “I just wanted to be a support to this project.”

Meanwhile, De Mornay’s praise for Cruise comes amid rumors that the “Cocktail” actor is dating Hollywood starlet Ana de Armas.

The pair first sparked romance rumors in February, and they were most recently spotted enjoying time together on a yacht in Menorca, Spain.

However, insiders close to the 37-year-old “Knives Out” actress have insisted that Armas is single and simply preparing for a project she and Cruise are currently working on together.

“Tom is crazy hardworking, and she’s very excited to work with him,” a source told People on July 18. “She calls it an opportunity of a lifetime.”

“Tom is an incredible mentor to Ana,” they added. “She has nothing but amazing things to say about him.”
