Radar Online reports that Travis, 25, told Jenner, 20, that they are not compatible.
'He finally plucked up the courage to tell Kylie he’s done, that he loves her and will always be around for the baby, but they’re not compatible as a couple. Kylie was totally blindsided even though everyone else in her life saw this coming,’ says a source.
'She’s still refusing to admit it’s over, and begging him to stick around.'
Kylie and Travis began dating in April following her split from ex-beau Tyga.
