The Keeping Up With the Kardashians star, 18, kept it casual with minimal makeup, braids like her sister Kim Kardashian's, a black bomber jacket and black gym shoes. She was spotted out at dinner in Calabasas, California, and shared several Snapchat videos that showed her hanging out with her crew at home.
Meanwhile, Tyga hung out Friday night with a pal at a basketball game between the Los Angeles Lakers and Oklahoma City Thunder at the Staples Center in L.A.
On Friday, Us Weekly exclusively confirmed that Tyga, 26, had cheated on her with Brazilian model Annalu Cardoso.
The "Stimulated" rapper and model, 23, met on the set of one of his video shoots. She also later appeared on his MTV2 show, Kingin' With Tyga.
"Tyga is very careful and waits until Kylie is out of the country," the source told Us.
Last November, Jenner shared a humorous post in which she hinted that she checks Tyga's text messages.
Jenner and Tyga began dating in August 2014, after the rapper threw the reality star a 17th birthday bash. However, the insider also confirmed that Tyga and Cardoso began dating in December that same year.
"He would text her and ask how she was doing, casual conversation," a second insider said. "Then he started asking her to send pics and to meet up. They hooked up a couple of times, but for the most part they would just hang out."
The source also added that Tyga stopped seeing Cardoso after he feared their relationship would go public.
"He used to find a way to see her, and that stopped," the source added. "They never officially stopped seeing each other, but she’s stopped talking to him."
