Tom Cruise’s girlfriend Hayley Attwell wows in fashionable outfit at art exhibition

, who recently rekindled her romance with her Maverick co-star Tom, 59, rubbed shoulders with model Lila Moss, 19, and pop star Anne-Marie, 31, at the bash in Piccadilly.

She will help Tom celebrate his 60th birthday next month at two lavish parties – one in the UK and one in the US.

The Sun revealed this week that Tom will throw TWO A-list bashes in true superstar fashion – one in the UK, where he will take over luxurious members club Soho Farmhouse in The Cotswolds alongside British pals including co-star Simon Pegg, and a second in America – jetting straight across the Atlantic on his own private jet to be at both bashes in a matter of days.

A source added: “Tom is classy and low-key, despite his fame, but this is a big milestone and his friends and team want to mark it properly, so it’s seriously A-list – and there are two parties.

“In Britain the invite list will be a Who’s Who of his circle – they’ll be asking the likes of David Beckham, James Corden, his co-star Simon Pegg, and obviously his partner Hayley Atwell will be there for both.

"It’s going to be at Soho Farmhouse, where Simon had his party, and Tom just loved it – so he wanted to do the same again and take the place over.

“It’ll be very A-list, but also a lot of the team who he has worked with on Mission Impossible and Top Gun because they’ve become his closest friends.

"He also has such a good relationship with Prince William these days it’s possible he would come along too, he’ll be invited – but that’s a bit more dependent on the royals’ commitments.

“Then he’ll jump in his Honda jet from Biggin Hill in Kent back to the US and do it all again with his American friends.

"It’ll be a bit of a Hollywood who’s who.”
