Rebecca lets loose with boyfriend on airplane!

David Beckham's ex PA Rebecca Loos, who hit headlines with her alleged affair with the soccer ace, has now landed herself in trouble for descending on her lover Matthew Ridge in full view of shocked airline passengers.

Fellow flyers flew off the handle when they saw the celebrity taking on her rugby star on a transatlantic flight.

Rebecca and former All Blacks ace Ridge had to be stopped in mid-flight by the crew after other passengers complained about their behaviour.

"It was pretty obvious what was going on. With all the noise in the cabin I couldn't hear much but it certainly looked like he was groaning," a fellow passenger was quoted by the Newsoftehworld, as saying.

The pair travelled business class on Air New Zealand's flight NZ1 from London to Los Angeles .

"As soon as Rebecca's wine glass was full, she headed over to see Matthew. She climbed into the bed and lay on top of him. I tried to ignore it and go to sleep but I could hear her giggling. They started snogging and then she disappeared under the blanket. She later came up for a kiss but then they were at it again. But this time the blanket fell onto the floor. I was shocked — it was then the steward told them to knock it off," she added.

Loos hooked up with Matthew last October when they appeared together on a TV show Down Under. He later dumped his girlfriend Keita Nobilo to bed David Beckham's ex-lover.

An Air New Zealand spokesperson confirmed: "There were complaints in the premium cabin on NZ1 that required a couple of passengers to modify their behaviour."

However Matthew's agent, Mick Watson said, "They're a couple, they were on a plane and something obviously happened. Matthew apologised to the crew and Rebecca went back to her bed. What's the big deal?"
