The 'Keeping Up With The Kardashians' star is reportedly desperate to go one better than her ex-wife - who was known as Bruce Jenner before undergoing a gender transition - and is working hard to get in shape.
A source said: ''Despite what they say, Kris is fighting with Caitlyn because she's still so upset that Caitlyn has captured the spotlight.
''So she's working out a lot to get in shape and get skinnier in order to compete with her ex ... [She wants] to look better than Caitlyn.''
And it's not just increasing her work out regime, the 59-year-old matriarch is also considering a new hairstyle and a big wardrobe change.
The insider added: ''She's talking about ditching her signature short pixie and getting extensions, like Kim [Kardashian West; her daughter] and Caitlyn.
''She wants a sexy new look, including a revamped wardrobe. She's admitted she can't stand that Caitlyn looks better than her.''
The whole family have started working on their image to improve the ratings on their E! show.
The source told RadarOnline.com: ''The whole family is trying to look the best they ever have and they hope that looking fabulous will boost ratings and give their show the fresh feel it really needs.''
