Rob Lowe has opened up about Gwyneth Paltrow's surprising revelation that his wife taught her how to perform oral sex when she was a teenager.

In an interview about the admissions with ET, Rob said he never saw it coming, explaining that he had no idea that his wife Sheryl Berkoff had given Gwyneth this advice back in the day.

"I'm telling you, listen, when I say it's intimate conversations… I would never pull one over on my fans," he said about his honest podcast.

Rob added: "You know, GP, she throws it down… GP calls me and… I was not aware of that story. But can I just say, it doesn't surprise me."

Rob said that afterward, he warned his wife that she might become a topic of conversation after the admission.

"I was like, 'Love bug, you are probably going to get some attention, but I am a journalist now and I can't self-edit freedom of the press, of the speech. I am just not your husband now, I am a certified journalist'," he joked.

This comes after Rob Lowe's son weighed in on Paltrow's revelation about his mother.

Taking to Twitter to reveal how his mother embarrassed him, John Lowe tweeted a picture of an article that read: "Gwyneth Paltrow reveals the sex tip she piked from Rob Lowe's wife."

"2020 has been a wild ride, but this has settled it for me. I choose death by murder hornets," John wrote in response to the article, referring to the deadly insects that hit the headlines back in May.

Paltrow made the revelation this week to Lowe on his Literally! With Rob Lowe podcast, where she said that his wife Sheryl Berkoff, a makeup artist, taught her "how to give a blow job" back when she was still a teenager.

The 57-year-old actress said that she befriended Lowe through Berkoff, who Paltrow had previously met when she did makeup for her mom Blythe Danner.

"I met Sheryl when I was 15 or 16," the Politician star said. "She was doing my mom's makeup on this TV movie, and I went down to visit. It was in Florida. I met Sheryl, and I was like immediately obsessed with her."

"First of all, she was dating Keanu Reeves, who was my celebrity crush. And she was so cool," Paltrow continued. "And she knew that I was sneaking cigarettes, and she would come smoke with me behind the trailer, and she taught me how to give a blow job, and you know, all the classic Sheryl stuff."
