Kylie Jenner, 22, has kept tight-lipped on the reason for her split from Travis Scott but her grandma Ester, 93, says it is because the rapper did not 'commit enough' to the make-up mogul.

The couple, who share one-year-old daughter Stormi, revealed they ended their relationship in October and claimed they would remain friends for the sake of their little one - but neither have opened-up on what exactly broke them.

Caitlyn Jenner 's mum has now shared how she 'sympathised' with Kylie when her relationship ended, as 'Travis should have proposed.'

“Young people today, they think they can live together, start a family together, without being married, it doesn’t work! I don’t know.”

It comes after Kylie and rapper hunk Drake sparked rumours that they're dating after they started spending more time together recently.

Reports of their suspected blossoming romance had also reportedly upset Travis.

It was then claimed that Drake dumped her because he is more of a "free spirit" and didn't want to be tied down.

But in a shocking twist, a source has claimed Kylie’s budding courtship with the God’s Plan artist is continuing "occasionally" and is actually all a ploy to make her baby Stormi’s dad jealous.

“Kylie doesn’t seem to be dating,” a source told PEOPLE. “She sees Drake occasionally, but it doesn’t seem serious.

“She could be doing it just to make Travis jealous.”

Kylie, who split from Travis Scott at the beginning of October, and the Canadian rapper were first linked in late October when the beauty mogul went to his 33rd birthday party.
