She's had a beautiful daughter, married the man of her dreams and happily settled into family life, but three years on from her relationship with Reggie Bush, Kim Kardashian's ex is still a sore talking point in the Kardashian household.
The KUWTK dated the handsome Detroit Lions player for three years between 2007 and 2010 before eventually settling down with Kanye West and tying the knot in May.

But reminders of her past relationship arose recently after Reggie married his fiancée and mother of his daughter, Lilit Avagyan, earlier this month in an intimate wedding in San Diego, causing tension among Kim's family
Insiders claim that the mother-of-one went out of her way not to read about the intimate nuptials on July 12 that her step-brother Brody Jenner attended, despite skipping her own Florence wedding in May.
"Kim went out of her way to avoid reading about Reggie's wedding to Lilit last weekend," an insider told Radar Online.

The publication also claim the reality star has imposed a ban on discussing the NFL star in the Kardashian-Jenner household due to fears it will make Kanye "jealous".
"She doesn't like to discuss Reggie, not even with her sisters. And Kim did remind her family to not mention Reggie's name in front of Kanye, because he is very jealous of him.
"There have been numerous assurances by Kim that Kanye has nothing to be jealous of, but there is always an argument when his name comes up," the source added.

"Kanye thinks that Reggie is still in love with Kim because he married a woman that looks exactly like her. And honestly, that isn't lost on Kim either."
There were rumours that Kim was left devastated after her ex-flame Reggie confirmed he was having his first child with Lilit back in 2012.
At the time insiders alleged that the brunette beauty was upset by the fact Reggie never showed her the same commitment despite her wanting to marry and start a family with the 29-year-old.
