Olly Murs, Emma Bunton and Mark Wright are among the stars who donned bright headwear and clothes for charity.

The trio were joined by Elijah Wood, Ed Sheeran, Ellie Goulding and Little Mix, who lent their support to Global’s Make Some Noise day. This year’s theme was “dress loud”.

X Factor host Olly donned a clashing Hawaiian outfit, as he posed for photos with Gold radio presenter Tony Dibbin, while Emma – a presenter on Heart – wore a huge bow on her head.

Olly’s mission was to crash all eight of Global’s stations in an hour – Capital Xtra, Radio X, Classic FM, LBC, Heart, Gold, Smooth and Capital.

Australian boyband 5 Seconds Of Summer created and designed their own headwear.

Thinking Out Loud singer Ed surprised a fan, who has acute lymphoblastic leukaemia.

The charity day raised nearly £2 million for Make Some Noise.
