The soap star is one of four rumoured to be in this year's line up, with a total of twelve celebrities set to enter during this Thursday's launch show.
Ryan will be joined by Corrie’s Sam Robertson, and Tricia Penrose from Heartbeat and ex EastEnder Gillian Taylforth who have all also been linked to the series.
A “programme insider” told The Sun newspaper last month: “Whatever way you look at it, soap operas are really successful.
“Having so many stars from those shows can only be a boost for the Big Brother house.”
Seeming to confirm his spot in the CBB line up, Ryan tweeted this week: "Tweeps… I’ll be on a hiatus for a little while. My manager will be covering all interactions on my account. Peace and love! #CBB”
Also linked to the upcoming show is comic Jim Davidson and singer Meat Loaf, who has revealed details of a new UK Arena tour shortly after the show is due to end.
X Factor’s Rylan Clark has apparently been offered £250,000 to take part, although the show may clash with The X Factor’s live tour in the new year.
Steps singer Claire Richards, The Hills stars Spencer Pratt & Heidi Montag and model Lacey Banghard have all also been rumoured.
Celebrity Big Brother starts on Thursday night at 9PM on Channel 5.
