X Factor finalist and Celebrity Big Brother winner Rylan Clark has confessed that he had a pregnancy scare with presenter Caroline Flack after waking up in bed together one morning.

Speaking to radio station Capital FM, the singer and personality explained that after a particularly boozy X Factor wrap party they ended up sharing a bed and woke up with foggy memories of the evening's events:

"I woke up in the morning underneath Caroline Flack and we were like: 'Did we?' And she went: 'I don't know'."

'And I went: 'Are you pregnant?' She said: 'I don't know,' and I was like: 'I'll get a Clear Blue!'"

Meanwhile, Heidi Montag, who took part in CBB with Clark, has explained that she plans to duet with the singer now that they're both out of the house: "I'm going to do a duet with Rylan. I like Rylan, just not living with Rylan and especially playing a game against Rylan; but in real life."
