People know something's not right between Travis Scott, 25, and Kylie Jenner, 20, when Kanye West has to get involved.

The "Famous" hitmaker had some words of advice for Scott about spending time with Jenner while she is pregnant with their child.

Kanye West Asks Travis Scott To Man Up

A source close to the Kardashian clan revealed to Hollywood Life that West tried to talk some sense into Scott about being present in Jenner's life, especially during the last few months of her pregnancy.

The source said that West had a serious one-on-one conversation with Scott about making a family and fatherhood at the Kardashians' Christmas celebrations earlier this week.

The insider also pointed out that it was an emotional conversation between the two rappers. West told the "Butterfly Effect" hitmaker how wonderful it feels to become a father and how he will experience positive changes in his life after the arrival of the baby. Jenner is reportedly due in February but still has not confirmed her pregnancy.

The source mentioned that although the pair shared a beautiful conversation that revolved around fatherhood, West had to make an important point to the young rapper.

"Kanye made it clear to Travis that he needs to step it up big time," the source added. "Kanye is protective of all of his family and wanted Travis to know that he better not let Kylie down in anyway once the baby arrives, 'cause Kanye will be watching."

The insider also noted that Scott does not want to let West down as he considers the Yeezy designer as his idol.

Jenner Worried About Scott Cheating On Her?

West's little chat with Scott does not come as a surprise given how worried she is off late about her beau cheating on her. The Keeping Up With the Kardashians star is losing confidence in her relationship with Scott after he was spotted at a strip club last week.

Jenner got pregnant weeks after she and Scott started dating and now she's feeling vulnerable as her due date is only two months away. She is worried that Scott will cheat on her with another woman.

 "Kylie is feeling very vulnerable right now, between the pregnancy hormones and being so isolated all the time she's already on edge," a source told Hollywood Life last week. "And then add in the drama with Travis and it's almost too much for her to take."
