BBC bosses have reportedly been ordered to change the title of celebrity gymnastics competition Let's Get Ready To Tumble - to avoid risking the wrath of Ant and Dec.
The broadcaster confirmed details of the upcoming show - which will see world-class gymnasts tutoring various stars in their sports - in an announcement last October.
It was due to be called 'Let's Get Ready To Rumble' in what was thought to be a nod to Ant and Dec's hit single 'Let's Get Ready To Rhumble', which shot to number one in the singles chart last year after they performed it on Saturday Night Takeaway.
However, The Sun says - in what could be an April Fools' joke (in which case we've fallen for it hook, line and sinker) - that executives are now considering new names after lawyers warned the working title could result in trouble with the Geordie duo.
Never mind legendary American boxing announcer Michael Buffer, who trademarked his signature catchphrase 'let's get ready to rumble' in 1992.
The newspaper's source said: "It works but it’s too similar to Ant and Dec’s song so everyone was worried it would cause problems. They are working on a new name – so it could just end up being called Tumble."
The new show is the BBC's attempt to muscle in on the recent trend of sports reality TV, which started last year with ITV's Splash!, in which Olympic diver Tom Daley coaches celebs in diving.
Channel 4 then joined the fray this year with The Jump, a winter sports-themed contest - which they're set to bring back for a second series despite four celebs pulling out of the first run due to major injuries.
'Tumble' is set to air later this year on BBC One.
