Cheryl Cole and Gary Barlow are among a group of celebs who've climbed to the top of Africa's tallest mountain to raise loads of money for Comic Relief.
Their mammoth trek up Mount Kilimanjaro in Tanzania has helped to raise almost £1.4 million for the charity.
Cheryl and Radio 1 DJ Fearne Cotton were among the first to reach the top of the 19,300ft peak early on Saturday.
The rest of the group, including Radio 1 DJ Chris Moyles and pop star Alesha Dixon, followed them a bit later.

The group's Comic Relief blog of the Red Nose Climb said: "Ben [Shepherd], Fearne, Denise [Van Outen] and Cheryl make it just as the sun comes up. Amazing."
Eight of the group arrived at the top within 40 minutes of each other.
Alesha fell behind as she struggled with muscle pain and altitude sickness, but she refused to give up and caught up with the others two hours later.
Jeremy Lane, who led the celebs in their challenge, said he'd never met a more determined group.
"When the going got tough their camaraderie was unbelievable," he said.
"No-one should under estimate how gruelling this climb is."
