The 36-year-old, who already works under the network as a presenter for them, reportedly can't wait to strut her stuff for viewers on a Saturday night from the ballroom.
The news was confirmed on the official Strictly Instagram account this morning.
A photo of Clara was shared with the caption: "Hey DJ! We can't wait for @bbcradio1's @claraamfo to hit the dance floor. She's spinning straight into #Strictly 2020."
It was reported last month Clara was in talks with BBC bosses to star on the popular dance competition.
Max George, Caroline Quentin and Jason Bell and GMB's Ranvir Singh are also so far confirmed for the show.
Last month when asked by The Sun if she'd go on the show Clara remained coy.
She said at the time: "It's an amazing show and I'd be honoured if they asked me, I'm just a fan of the show."
Clara continued: "I've got friends who've done it – Dev [Griffin] from Radio 1 did it and he was robbed. It's such an amazing show but I'm just a fan."
An insider had previously told The Mirror : "Clara is now a familiar BBC face and producers want her. The show wants to cast a diverse range of talent."
She rose to fame when she joined BBC Radio 1Xtra in 2013 and after impressing listeners and bosses alike she took over from Celebrity Juice's Fearne Cotton as the host of the station's mid-morning programme in 2015.
