Kris, 61, called time on her relationship with Gamble earlier this year in order to focus on her family.
But it seems she's had a change of heart and the pair appeared to be inseparable on the red carpet at the Race to Erase MS Gala in Los Angeles, reported Daily Mirror.
Corey, 36, was dressed in a black suit to co-ordinate with Kris.
The news come after it was revealed the current season of "Keeping Up With the Kardashians" has attracted its lowest ratings ever and Kris is said to be keen to get the show back on track.
