The reality TV star grew close to Smith's wife, Racquel, while she was dating REGGIE BUSH, who played alongside the athlete on the New Orleans Saints.

Smith was gunned down in an apparent road rage incident after a car crash in New Orleans on Saturday (09Apr16), when Racquel was also shot in the leg.

She was hospitalised with non-life-threatening injuries, and Kim took to social media over the weekend to send her condolences to the Smith family.

She posted a photo of herself alongside Racquel and captioned it, "My heart breaks for my sweet friend Rockie. I'm deeply saddened by your loss. Will, you were an angel to your family on earth and you will continue to be in the life after. May God bless you! Sending so many prayers to her and her family!!! May the Lord surround her and her children with love and protection during this devastating time."

Now Kim has travelled to New Orleans to be by Racquel's side after she underwent surgery on Sunday (10Apr16). Kanye West's wife was photographed catching an overnight flight out of Los Angeles on Monday night (11Apr16), reports

Police have arrested shooting suspect Cardell Hayes and he was booked on a second-degree murder charge on Sunday (10Apr16).

Kim dated Smith's teammate Bush from 2007 to 2010.
