Nicole Scherzinger is angry with boyfriend Lewis Hamilton after it emerged he partied with a group of 10 women in a penthouse hotel suite earlier this week.
The racing driver had been out with American rapper J. Cole before heading back to London's May Fair Hotel with the party - which included a couple of his long-time friends, staying up dancing and spraying champagne until 5.30am.
The former Pussycat Doll, who is now a judge on the UK version of X Factor, is said to be 'angry and embarrassed' by the normally straight-laced Hamilton's behaviour.
A source said: 'Yes she's angry, he's embarrassed her. It's not his typical behaviour, but of course she's not happy. However she knows he hasn't done anything wrong, but she's angry that he's been seen out like this while she's back in America.'
Claudia Martinez and Emily Tudor, who were among the guests invited back to the hotel, revealed to The Sun that Lewis was having so much fun at the penthouse suite in the venue he even sprayed the walls with champagne.
Emily said: 'It was huge, there was a kitchen, two bathrooms, two bedrooms and a huge lounge. Lots of people were chilling in the main room, people were smoking on the balcony.
'At one point, Lewis was spraying champagne all over the room like he had just won a race.'
Hamilton raised eyebrows after he was seen kissing a woman, later revealed as old friend Phreeda Sharp (pictured below).
He tweeted soon after: 'Phreeda is like my sister, a good mate to me n Nicole. Can't say goodbye 2 friends without it being seen as a mystery kiss.'
Nicole - who is currently in Los Angeles - is at present readying herself for her new role as a judge on the UK version of the X Factor.
The couple have struggled at times to make their long-distance relationship work because of Hamilton's jet-set lifestyle as a Formula One driver.
