Gary Barlow, Twiggy, Myleene Klass and Dannii Minogue all look thrilled to be taking part in a Diamond Jubilee garden party.
The celebrities can be seen enjoying summer-time festivities including an egg-and-spoon race and a barbecue for Marks & Spencer's new TV advert.
The Jubilee theme is topped off with Take That star Gary singing The Beatles classic Here Comes The Sun.
The singer said: "It's real a privilege to cover such an iconic track.
"You can't better perfection but I hope we've given it a modern twist that will capture the mood of the nation and provide the perfect anthem for summer 2012."
The advert will air for the first time on April 5 on ITV1.
