Kylie Jenner, who rarely shows her emotions, breaks down crying in an emotional sneak peek of Keeping Up With the Kardashians' Sunday, February 14, episode. In the clip, an inconsolable Jenner, 18, can barely get words out to explain to her older half-sister Kourtney Kardashian what’s wrong. 

“Did you guys get in a fight?” Kourtney asks a sobbing Jenner, referring to her boyfriend, Tyga. “I just, like, don’t know what to do about T,” the makeup maven tells her sister through tears.

The moment appears to be from around when Jenner and the rapper briefly split in November 2015. As previously reported, Jenner called it quits with Tyga on his 26th birthday and deleted all but one Instagram photo of herself with the “Rack City” singer on her social media account.

Despite rekindling their romance since then, the drama hasn’t died down between the two.

Us exclusively revealed last month that Tyga cheated on Jenner with a Brazilian model named Annalu. According to sources, Blac Chyna’s ex-fiancé is “careful and waits until Kylie is out of the country.”

The pair, who went public with their relationship when Jenner turned 18 in August 2015, have stayed relatively out of the spotlight since the news broke, but were last spotted having dinner together at Craig's in West Hollywood on Sunday, January 31.

Watch the emotional moment above.

Keeping Up With the Kardashians airs on E! on Sundays at 9 p.m. EST.
