Rylan will be performing on every date of the X Factor live tour later this month, despite it starting the day after the CBB final.
It'll give Rylan less than 24 hours, assuming he makes the final, from the end of Celeb Big Bro before the first performance on the tour, which is in Manchester.
Evicted CBB housemate Gillian Taylforth let slip yesterday that Rylan had been leaving the house to rehearse.
Blabbing on The Wright Stuff, the soap star claimed that the X Factor singer had left "every Sunday" to practice.
She revealed: "Rylan went out to do X Factor rehearsals... obviously he wasn't allowed to talk about it, but when he came back he'd just ask somebody the time very quickly like [his] driver, and we said to him when he'd get in, 'What's the time?'"
A spokesperson for the show commented: “Rylan has rehearsed for his tour on site with a choreographer, escorted by a Big Brother producer.”
And in a longer statement read out on last night's spin off show Bit On The Side, Channel 5 said: "It was agreed before Rylan entered the Big Brother house that he would be allowed to rehearse for his tour twice on-site with a choreographer.
"This was agreed on the strict understanding that he was not allowed to discuss events in the Big Brother house with anyone during such rehearsal periods.
"Rylan was escorted by a Big Brother producer at all times during rehearsal to ensure full compliance."
