Gwyneth Paltrow made a risqué joke about Hailey Bieber's father Stephen Baldwin during her appearance on the model's vlog, Who's in my Bathroom.
The 49-year-old cheekily quipped about Baldwin, 56, while reflecting on their time together at work on the 25-year-old model's youtube channel.
Paltrow co-starred with the actor in Alan Rudolph's 1994 Dorothy Parker biopic, Mrs. Parker and the Vicious Circle, and said Baldwin was "so nice" during their time on set.
Hailey responded by saying she "likes hearing" nice stories about her dad and said "imagine if you had some horror story", to which the actress then jested "like, f***** your dad in the bathroom?".
The shocked model replied: "I’ve had that happen to me actually. I don’t know if he even knows that I know that. But I’ve had that happen," before Paltrow confessed that she was joking.
Check out her vlog below:While the Goop founder was quick to assure Hailey that she didn't in fact sleep with her dad, she did confess to another sexual faux pas when she mistook the model's signature glazed donut skincare routine with something a little racy.
Hailey was introducing her Rhode Peptide Glazing Fluid when Paltrow asked "Glazing Fluid? What are you glazing?"
Hailey then explained: "I know you're curious about this glazed donut concept…For me, it's about the look - that sheen, that glowy, glazy sheen. I don't want to go to bed at night unless I look like a freshly glazed donut."
The Iron Man actress was baffled and replied: "Oh... Okay. Got it," before Hailey asked "Why? Where did your head go?”
"First it went to, like, does that mean someone wants to lick your face?" explained Paltrow, "then I thought glazed donut sounded sort of… sexual?".
However, Hailey took it all in good stride, and joked: "Ha! You're like 'what’s this new position everyone's getting into? The glazed donut?!'" and then spoke about all the ingredients in the product, such as "gel-hybrid serum," "peptides" and "hyaluronic".
Elsewhere in the video, the se7en actress - whose godfather is Steven Spielberg, mother is actress Blythe Danner, and father is producer Bruce Paltrow - spoke on the advantages and disadvantages nepotism can give you in the show business.
"As the child of somebody, you get access that other people don't have. So the playing field is not level in that way," she began.
"However, I really do feel that once your foot is in the door, which you unfairly got in, then you have to work almost twice as hard and twice as good because people are ready to pull you down and say, 'You don't belong there. You're only there because of your dad or your mom' or whatever the case may be," she continued.
She said that the negativity "shouldn't limit you" or have an impact on "your path or the decisions that you make", to which Hailey responded: "I agree. I need to hear this today."
