The current 'Celebrity Big Brother' champion was linked with the role after audience ticket company Applause Store tweeted: "#BB13 @bbuk with @Emma_Willis + @RylanClark".
The offending tweet was then quickly deleted. Hmmm.
Rylan - who was previously linked to a co-hosting role on 'The Xtra Factor' - later addressed the rumours on Twitter, writing: "Lot of stories today, I've not made any decisions yet as to what I want to do. All just rumours at the moment x."
It was announced on Tuesday that former 'Bit On The Side' host Emma has been promoted to the host of the main show after Brian Dowling was axed from the role.
Davina McCall - who served as the Big Brother's presenter for 10 years on Channel 4 - congratulated Emma on her new role yesterday, writing: "well done emma xxx".
Emma tweeted back: "thank you lovely lady xxx", to which Davina replied: "woop woop!!!"
The 'Big Brother' returns in the summer, followed straight by another celebrity edition.
