The happily married beauty, who only recently welcomed a baby with footballer husband Jamie Vardy, has entered the ITV show alongside celebrities such as Vanessa White, Georgia Toffolo and Amir Khan.
But years before heading onto the show, it seems Rebekah had a fling with another famous face.
The mother-of-four apparently had a night of passion with 44-year-old Peter Andre, long before he settled down with beautiful wife Emily MacDonagh.
Talking about the fling, Rebekah, now 35, told The News Of The World about what she claims happened in 2001.
The fling was said to have taken place at the Burnham Beeches Hotel in Buckinghamshire, after the duo met in a popular restaurant.
She then publicly spoke about the encounter three years later.

She said in 2004: “He had great muscles and I thought he’d be a great lover. But he was the worst lover I have ever had.
“He didn’t even attempt to satisfy me.”
OK! Online have contacted a representative for Peter Andre for comment.
Rebekah is now in a happy relationship with Leicester footballer Jamie Vardy.
The skilled sportsman rose to monumental fame when he helped win the Championship and secure promotion to the Premier league in 2014.
Once the news was confirmed that Rebekah was entering the jungle, husband Jamie tweeted to his 596k followers: “So proud @RebekahVardy Go and smash it in the jungle.”
