In her second Tweet, Kylie addressed her split with rapper Travis Scott (with whom she shares one-year-old daughter Stormi Webster).
"Travis and i are on great terms and our main focus right now is Stormi !! our friendship and our daughter is priority," the Kylie Cosmetics founder stated.
According to People, the couple is working through "several issues," as their differing lifestyles put a strain on their relationship.
A source told the publication that "Kylie is all about family life and really wants a second baby."
Following the news of their split, the Keeping Up With The Kardashians star was photographed looking downcast as she left Delilah with her friends Anastasia 'Stassi' Karanikolaou and Kelsey Calemine.
While the couple has been romantically linked since meeting at Coachella in 2017, the source added that the rapper "isn't ready" to give Jenner "all that she wants."
"She still has trust issues with Travis. He hasn't been giving her the commitment that she needs."
The mogul allegedly is looking for a relationship like her sister Kim Kardashian and her husband Kanye West.

According to TMZ, Travis and Kylie's last public appearance together was at the premiere of his Netflix documentary, Travis Scott: Look Mom I Can Fly in August (they also recently posed together for Playboy).
