Brad Pitt and Angelina Jolie's Midsummer Night party

Brad Pitt and Angelina Jolie have invited George Clooney and Jamie Oliver to a Midsummer Night party at their Surrey home.

The Hollywood pair, who are engaged and raise six children, have also invited Clooney's girlfriend Stacey Kiebler to the event.

'Brad and Ange hold a Midsummer party every year and always base the theme around a specific country because it's a great learning opportunity for the kids,' an insider reportedly explained.

'They've done Australia, Russia and Germany in the past but as they're living in London they've really got into the spirit of things with the Jubilee and the Queen's birthday.'

The source continued: 'It'll be like a British fete, with all the traditional games and cream teas in the garden in the afternoon.'

Brad and Angelina are also hosting their own Olympic opening ceremony party, with the likes of the Beckhams and the royal family to reportedly attend.
