Kanye West is reportedly upset after Mariah Carey and Beyonce Knowles' children spent time together. The 39-year-old rapper had previously revealed that his daughter, North West, has never played with Jay Z and Beyoncé's daughter, Blue Ivy.

The Vision of Love hitmaker posted a picture of herself with children, Monroe and Moroccan as well as with the Halo singer and Ivy. She wrote: "Backstage at Christmas time with our beautiful children.@beyonce#christmas #family #love"

A source told Hollywood Life: "Kanye flipped out when he saw the pictures of Beyonce, Mariah [Carey] and their kids together backstage at a show this week. All he wants is for HIS kids to be the ones playing with Blue. He didn't take it well when he saw Mariah's kids spending time with Blue instead of North."

The insider added: "He just wants to be accepted by his peers. He feels like his family is misunderstood."

Kanye threw shade at the 46-year-old media mogul during his Saint Pablo Tour at Key Arena in Seattle. He also slammed the couple for not reaching out to him after Kim Kardashian was assaulted and robbed in her Paris hotel room. The Keeping Up With the Kardashians star was held at gunpoint as the robbers stole an estimated $10 million of jewellery.

The Yeezus hitmaker said: "Don't call me, after the robbery, and say 'how you feelin'?' You wanna know how I'm feelin'? Come by the house."
