The 41-year-old singer-actress was rumoured to be taking part in the US reality dance show, along with Jersey Shore star Nicole “Snooki” Polizzi.
Entertainment website TMZ.com reported that the pair would be heading the celebrity cast, along with former Saved By The Bell actress Tiffani Thiessen.
But the Grammy Award-winning star took to her Twitter page to deny the rumours.
She tweeted: 'No truth to the rumours of me doing Dancing With The Stars. Love the show, though, so I'll be watching just like you!'
