Tottenham midfielder Lewis Holtby (above) chatted up an air stewardess outside a pub toilet and later had sex with her.
The 23-year-old Premier League footballer, who is dating Danish model Ann Charlotte, approached the unnamed stewardess in a posh part of East London, reported Britain's The Sun.
The 33-year-old woman said: "I saw him moving his stuff in with his parents and he caught my eye straight away.
"Later that evening, I was in a bar and he saw me and followed me to the toilets and told me he was a footballer for Spurs.
"He told me I was really pretty and we exchanged numbers.
"That evening, he sent me a text message just saying, 'Hi'. But they quickly turned sexual."
Holtby texted the woman: "Can u send me some of your sexy pix? I'll send you some too. I'll treat you like a princess."
The messages, which became explicit, continued and he sent her a photo of his torso and another of his private parts.
The stewardess said: "He's obviously quite proud of it. He's certainly not shy. He also sent me a pic of his face - he looks like Niall from One Direction."
Holtby persuaded her to see him one day after he had finished training. They made small talk and had sex for 45 minutes.
The stewardess said that the poor form Holtby showed on the pitch for Spurs - their fling was before he went on loan to Fulham - was not repeated in the bedroom.
With his transfer to Fulham, Tottenham chairman Daniel Levy could rake in a whopping £8 million (S$16.8 million) from Fulham for Holtby's transfer, reported Britain's Daily Mirror.
She did not hear from Holtby again and later read about his relationship with his girlfriend Ann online.
The player posted a selfie of him and Ann at Wembley as they watched England beat Denmark on March 5.
The air hostess added: "I felt so sorry for her. She deserves to know the truth about her boyfriend, before she commits to him any more. If he can cheat that easily with me, he'll do it again."
Holtby, who has said footballers should be role models, told The Sun: "I did a big mistake, the first big mistake in my life... "I can't look myself in the mirror. I have never cheated before."
