Rob Lowe has opened up about how his wife taught Gwyneth Paltrow how to perform oral sex.
Yep, the heartthrob discussed the fact that his wife Sheryl Berkoff was instrumental in giving the Iron Man star some tips when she was just 18 years old.
Speaking to Jimmy Kimmel, Lowe talked about his podcast, Literally! With Rob Lowe, and about all the amazing guests he has had over the course of its 90 episodes.
And he recalled how Paltrow dropped a particularly jarring bombshell during their conversation.
The 57-year-old said: "Here's the thing: The good news is my wife doesn't watch anything I do so she won't be watching this, so I can say it.
"When Gwyneth was a little, precocious 18 year old, my wife was still a makeup artist on a movie that Gwyneth's mother Blythe Danner was working on.
"Gwyneth came to visit and Sheryl would give her cigarettes and they'd go out and smoke behind the trailers. She was like a big sister to Gwyneth, still is.
"And, apparently, Gwyneth told me on the podcast, I had no idea but I must thank her, that my wife taught Gwyneth how to - how should we say this on network television? It's your show..."
To which Kimmel replied: "I think 'perform oral sex' would be the way to go. Which is a very nice thing for her to do."
Lowe then quipped: "Or, as I like to say, Chris Martin and Brad Falchuk, you're welcome."
Paltrow, 49, made the confession two years ago on Lowe's podcast, where she was explaining how she and his wife connected.
She noted how the pair met when she was 15 or 16 while Sheryl was working as a make up artist on Paltrow's mum's TV movie.
The actor said: "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.
"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.
"And I just worshipped her. I thought she was literally the coolest chick of all time. And she was so awesome to me.
"And I was a high school kid. Like, the fact that she loved me that much before I was anyone or anything, you know? Same with you."
