AceShowbiz - David Beckham's alleged mistress Rebecca Loos felt "so hurt" when she apparently found him in bed with another woman. The former personal assistant and model, 46, remembers she was at a party with the then-Real Madrid player, now 48, who was "hiding at the bottom of the garden" speaking to a Spanish model.

"That hurt. There was wonderful food, a samba band from Brazil and flowing champagne," Rebecca, who says she had a fling with David in the 2000s, told the Mail on Sunday about the alleged incident during a party at soccer legend Ronaldo Nazario's home on September 22, 2003.

Rebecca said the night then took a turn when David's wife, Victoria Beckham, 49, rang her mobile phone. She added, "She's upset because she's calling David and he's not answering."

"I said I didn't know where he was. And she says, 'Don't hang up, go and find him.' I was like, 'OK…' so it's a bit awkward. I went into the house and up the stairs and I saw David's two bodyguards outside a door."

Rebecca said she told the minders David's wife was on the phone, and one of the bodyguards promptly "disappeared" inside the bedroom.

She added, "When he comes back David is with him. I can see the model in the background lying on the bed. I can see it's a bedroom. I was fuming and I just looked at him, gave him the phone and said 'Your wife.' "

David allegedly spoke quietly to the Spice Girls singer before handing his phone back to Rebecca, who said, "I was so hurt. It was just this awful feeling and I thought to myself, 'You stupid fool.' But he had me, he had his claws into me, and I was at his beck and call."

Rebecca first revealed her alleged affair with the married athlete in a 2004 interview. She told Sky News at the time, "You have got to remember, he is a married man. What if he is at lunch with Victoria? You have to wait for him to come to you."

David has denied Rebecca's allegations, along with several other women who claimed they were romantically involved with the Inter Miami co-owner while he was married.

He said in his "Beckham" documentary recently release on Netflix, "I don't know how we got through it in all honesty. Victoria is everything to me. To see her hurt was incredibly difficult, but we're fighters. We needed to fight for each other and for our family. What we had was worth fighting for."

Rebecca is now a medical assistant living in Norway with her doctor husband Sven Christjar Skaiaa, who she married in 2012, and their two children - and said she was speaking out against the documentary in order to defend herself.

She added to the Mail on Sunday, "I also have a family and I also have children and they also have Google and they can also watch documentaries. "And I want them to know that their mother was brave enough to stand up against them and to stand up for the truth."
