Gwyneth Paltrow loved receiving X-rated act from Ben Affleck, new biography claims

Gwyneth Paltrow and Ben Affleck's dirty laundry is being aired in a bombshell new biography - allegedly, that is.

Claims about the former couple's bedroom activity have made it into Amy Odell's upcoming book, Gwyneth: The Biography, which will hit the shelves later this month.

And according to the New York Times bestselling author, the pair were particularly fond of a certain sex act - and Paltrow supposedly told her pals that she 'loved' it.

Odell claims that one of the Goop founder's close friends, makeup artist Kevyn Aucoin, dished the dirt on what her and Affleck got up to behind closed doors during their on and off three-year relationship which began in 1997.

The A-listers got together after meeting at a dinner party, before going on to star in Shakespeare in Love alongside one another, as well as the 2000 comedy, Bounce.

Reflecting on her time with The Accountant actor, 52, Paltrow previously said her parents weren't huge fans of their romance.

"I think they appreciated how he's super intelligent and he's really, really talented and so funny, but he was not in a good place in his life to have a girlfriend," she previously told Howard Stern. "I think they were okay with the two of us not being together."

After calling it quits, Paltrow went on to get together with Coldplay frontman Chris Martin, who she was married to for more than a decade before they 'consciously uncoupled' in 2014.

But before the 'Yellow' singer came into her life, the actress was completely smitten with Affleck - and his skills between the sheets, as she's previously described her ex as 'technically excellent' when it came to sex.

In Gwyneth: The Biography, as per Page Six, Odell claims: "It was the ribald side of her that her friends knew well but that the public didn’t see.

"She told Kevyn Aucoin in his London hotel room one day after lunch that she loved when Affleck ‘tea-b****d’ her."

Yep, you read that right - it might not be everybody's cup of tea, but apparently it was Paltrow's.

Odell has also written about what led to the demise of the mother-of-two's relationship with Affleck.

The author alleges that Paltrow got together with the filmmaker when he was 'struggling with alcoholism and a gambling problem', while claiming the actress' pals had 'reservations' about them being together.

According to Odell, Affleck 'didn't always reciprocate her affection', as she wrote: "He at times seemed more interested in playing video games with the guys at his house than being with Gwyneth."

The book also delves into Paltrow's childhood, her glittering career in Hollywood, her high-profile relationships and her lifestyle brand, Goop.

Odell claims she has spoken to more than 220 sources - 'including close current and former friends and colleagues' - to get the inside scoop on Paltrow's life.

Gwyneth: The Biography is set to be released on 29 July.
