Teenage girls spent a day running around after celebrities including tennis champ Andy Murray and billionaire Richard Branson for a charity tennis match.

Nearly 100 girls from Nonsuch High School for Girls and St Philomena’s Catholic High School for Girls spent the week acting as ball girls for the Queen’s Club Championships in Kensington.

After winning the Aegon Championships Andy Murray donated his £75,000 winnings to the Royal Marsden cancer hospital, in Sutton, where his best friend, Ross Hutchins, is a patient.

In aid of the charity and at the end of the championship Murray, Tim Henman, Boris Johnson, Jimmy Carr, Michael McIntyre, Richard Branson and Jonathan Ross all took turns on the grass courts to give Sutton’s ball girls memorable end to their week at Queen’s.

Funny-man Michael McIntyre surprised Nonsuch year ten Molly Johnson, 14, from Epsom, with his silly antics.

Molly said: "Michael McIntyre was asking for a towel and I didn’t have one so I just had to walk over to him and he grabbed the balls and put his face on them.

"I kind of just stood there because I didn’t really know what to do and he said ‘thank you’. I was really embarrassed.

"My mum and my brother were watching and were laughing."

This was the 21st year the two schools had provided ball girls for the championships and the girls often make good friends and stay in touch after the event.

It was the third year Greta Thompson, 15, from St Philomena’s Catholic School in Carshalton, had the chance to be a ball girl and she too has had her fair share of fun experiences.

She said: "Basically our job is to make sure the balls are at the right end so the players can serve. We have to add up game scores a lot. It gets easier with practise.

"Last year I accidently tapped Kate Middleton’s dad on the shoulder and asked him for the time.

"At the charity match [this year] Jimmy Carr said I made a good catch. They were so nice and Boris Johnson shook our hands.

"It is one of the best weeks I have ever had. I will never forget it."

Dee O’Reilly, assistant head teacher at St Philomena’s, praised the girls and said: "It is a great opportunity for our students. From September to June they are training and they are very dedicated."
