The 59-year-old matriarch who has been dating the 34-year-old music industry exec since Octorber reportedly dumped Corey a while ago.
The couple have been seen together severally at high-profile events in Hollywood over the last few months but haven't been seen together for a number of week now.
According to RadarOnline, a source confirmed the couple haven't been an item for sometime and it was obvious to everyone that Carey was her rebound following her divorce from her husband of over 20-years, Bruce Jenner early January.
"Kris is an opportunist and she has traded up men her whole entire life. She is always looking for something bigger and better," the source says.
Kris and Corey were lastly seen at New York Fashion Week in February.
Kris is yet to comment.
