It has been ten whole years since a bunch of celebrities first took on Mount Kilimanjaro for Comic Relief.
But now a whole new group of fresh faces, from Strictly Come Dancing favourites to pop superstars, have taken on the pain-staking challenge all to raise vital funds to transform the lives of vulnerable people and communities throughout the UK and internationally.
The nine famous faces flew out to Tanzania to take on the charity climb with Comic Relief film crews filming the ups - literally - and downs along the way.
Kilimanjaro: The Return is an hour-long special which will air on BBC One at 9pm on Wednesday, March 13.
Viewers will see all the drama the celebs faced when taking on the eight-day trek which saw them climb 19,000 feet.
Here's all you need to know about the epic challenge.
Which celebrities climbed Mount Kilimanjaro for Comic Relief?
Stars from the small screen, sport and politics all tackled, and successfully completed, the climb.
Strictly Come Dancing head judge Shirley Ballas, former MP Ed Balls, broadcaster Anita Rani, Love Island's Dani Dyer, Pointless host Alexander Armstrong, BBC Breakfast presenter Dan Walker, BBC NFL pundit Osi Umenyiora and Little Mix's Jade Thirlwall and Leigh-Anne Pinnock.
And it seems like they all became unlikely friends posting with videos and pictures posted on social media along the way.
Former Strictly contestant Ed celebrated his birthday on day three of the teams trek.
