The married couple leant on each other for support as they were doused in freezing water while presenting This Morning on Friday (22 August).
Rochelle looked a bit nervous as she prepared for her soaking. Well, we'd probably be a bit nervous too if we were wearing a gorgeous blue leather jacket with perfectly coiffed hair and flawless make-up.
Ahead of the challenge, she and Marvin nominated Phillip Schofield, One Direction's Harry Styles and Rylan Clark to do it next…
Why Rylan, you ask? Because he was the one about to pour the bucket of ice cubed water over their heads!
Poor Rochelle looked like she was in shock after the ice bucket was tipped on her head and visibly shivered as she spoke to camera afterwards.
"What a way to go out of our This Morning stint," she said, adding that she could feel her false eyelash moving. Oops.
So far, Phillip Schofield and Harry Styles haven't responded to Rochelle and Marvin's nomination, but Phillip had already accepted the challenge from Davina McCall so we know he's going to do it.
Rylan, meanwhile, has promised to complete his challenge.
The ice bucket challenge was devised by the ALS Association to raise awareness of motor neurone disease and funding for research into the disease. People challenged are encouraged to chuck a bucket of ice water over their head and make a donation to the cause.
