Kim Kardashian reportedly had a secret fling with Calum Best before she became famous. A source reveals to The Sun that the "Keeping Up with the Kardashians" star and the son of football legend George had an "intimate romance" when they were younger and both lived in Miami.

Kim was allegedly introduced to Calum through her step-brother Brody Jenner. The 36-year-old socialite enjoyed her fling with the "Celebrity Big Brother" star before she married music producer Damon Thomas in 2000, years before she became famous thanks to her leaked sex tape with ex-beau Ray J.

"Kim and Calum dated when they were a lot younger - they weren't in the public eye back then," the source says, before claiming, "The pair used to hang out in the same social circles and shared a lot in common as they both had famous fathers."

The source further asserts, "Calum was close pals with Brody and is still friends with him and Scott Disick today." Kim's allegedly still in contact with Calum even after she got married to Kanye West, as noted by the source, "Kim is obviously married now but Calum still keeps in touch with the family when he's in the states."

A representative for Kim, however, claims that the above story is false. The rep tells Gossip Cop that Kim and Calum "never dated" even though they attended school together.

Kim got married to Kanye in 2014 and the pair share two kids together, three-year-old North and one-year-old Saint. Calum, meanwhile, previously dated actress Lindsay Lohan, model Georgia Salpa and Sarah Harding.
