Kylie Jenner knows the power of a good breakup song.

Days after her split from 26-year-old boyfriend Tyga, the 18-year-old cosmetics mogul took to Snapchat for a sip of Beyoncé‘s Lemonade.

Using Snapchat’s zebra filter Friday night, Jenner lip-synced to the Grammy winner’s new breakup anthem “Hold Up.” “They used to hide from you, like to you, but y’all know,” she performed, before being cut off by a friend changing the song.

The Keeping Up with the Kardashians star then moved on, mouthing the words to “Losin Control” by Russ.

“Falling in love now, losing control now,” Jenner pretended to sing. “Fighting the truth, trying to hide.”

“Shoulda’ ended it before it started,” Jenner continued in another video. “All she ever got was broken hearted. He was cheating on her tryna’ flip it back on her like a victim.”

Jenner’s videos came hours after sources told PEOPLE that there had been tensions over trust issues between the couple .

According to a source, the two “were fighting a ton over stupid, petty bulls—” over the last few months, and “she was over it.”

The fighting, met with trust issues that “made her feel insecure about their relationship and her brother Rob Kardashian’s engagement to Tyga’s ex “Black Chyna, added tension to the relationship.

“He was lying repeatedly to her face and she just couldn’t take it anymore,” says the source. “She couldn’t trust a word he said.”

Jenner and Tyga were dating for two years before their split – though their relationship was often on-again and off-again. A source tells PEOPLE Jenner has no intention of reconciling this time around.
