Celebrity Big Brother's Calum Best enjoyed 'secret affair' with Kim Kardashian

According to reports, Kim Kardashian and Calum Best had a "intimate romance", bonding over their famous dads.

But now a pal of the pair has admitted that back in the day, before either found fame, they enjoyed a fling together after meeting because Calum is pals with Kim's step-brother Brody Jenner and (kind of) brother-in-law Scott Disick.

Earlier reports suggested the pair had dated when they were younger - but a Kardashian rep said the story was false.

The romance reportedly took place before Kim's first marriage to music producer Damon Thomas in 2000, and many years before her sex tape with former boyfriend Ray J was leaked in 2007. She even went in to the house to set a Big Brother task - and tell them off for their lack of cleanliness of course. There's a bit of a Hollywood clique. However insiders say the brunette beauty shouldn't count her chickens before they hatch, because she's still on shaky ground.

A round-up of Kim Kardashian's hottest (and most controversial) pictures.

The E! star is now married to rapper Kanye West and has two children with him - North, 3, and Saint, who she welcomed in 2016.

Calum - who shared the CBB house with Kim's ex Ray J - might be hiding something.

"Ray J knows all about it - he's met Calum before and they get on really well", they added.

The son of footballing legend George Best has seemingly had no trouble moving on having already wooed Jasmine Waltz prior to her secret eviction.
