USA - Is jealousy involved? Kylie Jenner (27) is said to have forbidden her boyfriend, actor Timothée Chalamet (29), to continue filming sex scenes!

The 29-year-old is currently promoting a film in which he plays a table tennis prodigy who begins an affair with his rival's wife - played by Gwyneth Paltrow (52).

As the US Sun now claims to have learned from insiders, the 27-year-old is said to have been anything but enthusiastic about the "sizzling on-screen chemistry" between Chalamet and Paltrow.

The 52-year-old spoke openly about the numerous intimate scenes in the movie.

Among other things, she said that there were many hot bedtime moments between the two. She was also surprised that there are now intimacy coordinators, because in the past they "just took their clothes off, went to bed and the camera was rolling".

However, the comments the 52-year-old made about her on-screen romance with Chalamet probably didn't sit well with Kylie Jenner.

According to a source close to her, the influencer does not feel comfortable seeing her partner like this.

The 27-year-old is also said to have started a heated discussion with the actor about his intimate scenes. The two are said to feel considerable tension in their relationship in general.

"Timothée has no problem being intimate in movies, but Kylie doesn't like it [...] and doesn't want him to do any more sex scenes in the future," says the insider.

It was previously reported that the 29-year-old had fallen head over heels in love with the billionaire and was even talking about getting engaged.

He is also said to have already chosen an engagement ring for her. They are also said to already be looking for real estate in Europe.

However, those close to Chalamet are not particularly pleased about the romance either. Two people said it would be a "terrible mistake" if the couple were to get married.

"Many of us don't understand how they get on and how they harmonize," said one family member.
