Kim Kardashian is reportedly unhappy after Beyonce announced that she and Jay Z are expecting twins. The couple are already parents to a five-year-old daughter named Blue Ivy Carter.

The Halo hitmaker shared a photo of her holding her bare baby bump on Instagram. Beyonce captioned the image: "We would like to share our love and happiness. We have been blessed two times over. We are incredibly grateful that our family will be growing by two, and we thank you for your well wishes. – The Carters."

According to Radar Online, the Keeping Up with the Kardashians star wants to steal Beyonce's spotlight. A source said: "Kim was shocked at the Beyonce news and she was totally checking it out and seeing how many people like the post. Then when her friend Chrissy Teigen started Tweeting that she was best friends with Beyonce, she was actually hurt and worried."

"While everyone was tweeting and sending congratulations to Beyonce and Jay Z, Kim and Kanye did not say one word about it on their social media," the insider added. "The fact that Beyonce is going to have more kids than Kim once her twins are born absolutely drives Kim nuts! Kim was totally trying to steal Beyonce's baby thunder yesterday."

"Kim is going to try harder than ever right now to get pregnant because she is constantly searching for a way to one up Beyonce," the source stated. "She seems so jealous that Beyonce is more famous than she is. It doesn't seem like Kim will ever, be okay with that."

It was a well-known fact that Kardashian and Beyonce do not talk to each other. The Grammy award winning singer and Jay Z were noticeably absent from Kardashian and Kanye West's wedding in Florence, Italy on 24 May 2014. The ladies were both at the 2014 Met Gala held at the Metropolitan Museum of Art in New York City, but chose to keep a distance from each other at the event.

Adding on, the couple's feud escalated after West threw shade at the 46-year-old media mogul during his Saint Pablo Tour at Key Arena in Seattle, for not reaching out to him after Kardashian was assaulted and robbed in her Paris hotel room.

Following that, on 20 November 2016, West again went on rant about the couple, and performed three songs before abruptly ending his concert at the Golden 1 Center in Sacramento, California. The 39-year-old Gold Digger hitmaker was later checked into UCLA Medical Center for psychiatric evaluation in Los Angeles.
