It's not long until Comic Relief 2019 - and we now know some of the stars who will be taking part.

On Friday 15 March, there will be a special programme at 7pm on 91Èȱ¬ One featuring shows, sketches and challenges, all to raise money for the charity.

Comic Relief works to change the lives of vulnerable people and communities both in the UK and abroad.

So what's happening for Red Nose Day this year?

One of the main Comic Relief challenges this year was a celebrity climb of Mount Kilimanjaro - the highest mountain in Africa.

The stars who took part are:

The group climbed the 19,000ft-mountain in February and their trip is being shown in a one-hour programme, on 91Èȱ¬ One on 14 March.

It took them seven days.

Before the climb Little Mix's Leigh-Anne said: "It's so amazing to be part of this challenge for Comic Relief. I can't wait to get to the top of Kilimanjaro, and knowing that we are doing it for Comic Relief makes it incredibly special."

Jade added: "The nerves are certainly starting to kick in for the climb, but I'm lucky I will have Leigh-Anne up there with me and I can't wait to get stuck in with everyone!"

The expedition takes place 10 years after another Kilimanjaro climb led by Gary Barlow, which raised £1.5 million for Comic Relief - Kilimanjaro: The Big Red Nose Climb. Chris Moyles, Fearne Cotton and Cheryl also took part on this trip.

We're used to seeing Strictly Come Dancing presenters Tess Daley and Claudia Winkleman presenting on TV.

But for Comic Relief they are putting their dancing shoes on for an epic danceathon!

They'll be dancing non-stop for 24 hours - and the best bit? As many of their celebrity friends as possible will be joining them for a dance too!

The dancing starts on 11 March and they'll try to raise as much money as possible until the music stops on 12 March.

Radio 2 presenter Sara Cox did it in 2017 and raised an amazing £1 million - so that's the record to beat!

We also know that Comic Relief 2019 is reuniting the cast of a classic film Four Weddings and a Funeral, which was originally made in 1994.

It is going to be called One Red Nose Day And A Wedding, and will feature Hugh Grant, Rowan Atkinson and Mamma Mia! Here We Go Again star Lily James.

It follows on from Red Nose Day Actually, which was follow-up to the film Love Actually, made for Comic Relief in 2017.

There will also be a special comedy gig taking place at Wembley Arena on 28 February, featuring Russell Howard, Jimmy Carr, John Bishop, Sir Lenny Henry and Alan Carr.

All of the profits from the ticket sales will be going to Comic Relief.

Howard said: "Gigs like this are great as they help Comic Relief raise vital funds that enable them to help people here in the UK and around the world."

There will be a special edition of The Apprentice, led by Lord Sugar and his trusty advisors Baroness Brady and Claude Littner.

We don't know which celebrities will be taking part in this yet, though.

As more information about what is happening is released, we will let you know.
