The Saturdays are bouncing back - by riding spacehoppers across London's Westminster Bridge.
The group, whose hits include Missing You and Notorious, straddled Malteser-style inflatables in their fundraising efforts ahead of Red Nose Day this month.
The girls are ambassadors for the sweet brand which aims to raise more than a million pounds for Comic Relief, with a contribution from special packs going to the charity.
They are encouraging people to let out their "lighter side" for the charity.
The group's Frankie Sandford said: "We loved taking part in this cheeky challenge for Maltesers and hope the nation will be inspired to something funny for money this Red Nose Day."
