“Keeping Up With the Kardashians” star Kylie Jenner and boyfriend Tyga might be on the rocks. The two haven’t been spotted at a public event in weeks and she mouthed a cryptic lyric on Snapchat Thursday.

The teenager played “Moving On” by Justin Bieber and silently sang the words: “And baby I be movin’ on/ And I think you should be somethin’/ I don’t wanna hold back, maybe you should know that.”

Tyga, 26, would occasionally appear on her Snapchat too, but since breakup rumors swirled the rapper has been absent from her social media presence. Jenner, 18, reportedly pushed her boyfriend aside so she could spend more time with her friends and family and work on her career. She also reportedly thought that Tyga harmed her brand.

The rapper was “hurt” Jenner brushed him aside. “She literally blew him off at every turn last week and he hasn’t gotten over it,” an insider told Hollywood Life Tuesday. “He doesn’t know how much fight he’s got left in him.”

In turn, he dissed her lip kit, which apparently has had shipping problems. “Tyga’s shaking his head at Kylie and her family saying he’s bad for her brand after learning her lip kits haven’t made it to customers,” an insider told Hollywood Life. “He sent Kylie a scathing text that said, ‘So I’m bad for your brand, but you and your mom ain’t sending people they lip kits. Lol. Smh.’”

While Tyga might not be happy with the E! reality star, sister Kendall is thrilled that the relationship is reportedly shaky. “Now that Kylie’s world doesn’t revolve around Tyga, she and Kendall are really close again,” an insider told Hollywood Life in a different story last week. "She’s not glued to the hip with Tyga, and that’s a huge relief for Kendall; She feels like she has her sister back.”

Neither Tyga nor Jenner have stated if their relationship is over. She probably will just post cryptic messages and videos for now, especially since she wrote in a blog post last month that she doesn’t want the public to know “every little detail of my relationship.”
