The Keeping Up With The Kardashian's star later shared another shot from the same shoot, showing them both laughing. She wrote: "Irreplaceable."

According to Hollywood Life, Tyga was upset with the images. A source said: "The topless pics of Kylie snuggling with Tyga looks super sexy and cool, but Tyga wasn't all that happy about them. He hates it when she poses topless, but she pushed it and insisted it was an artistic choice for her store."

"Ever since her glam make over, he feels like she's such an attention addict and the more bold she gets, specifically with nudity, the more attention she gets. For Tyga, it was like she pulled a scab off an old wound," the insider added.

"Kylie's half naked photos really bug him, he's trying not to start a fight during his birthday," the source said.

This comes after the model was hit by pregnancy rumours. She was seen heading to Dr. Crane's office in Los Angeles, the same doctor who delivered Kourtney Kardashian, Kim Kardashian and Blac Chyna's babies.
