Celeb news: Beyonce and Kim Kardashian are friends. And their fans aren't happy.

Beyonce is married to Jay-Z. Kanye West is dating Kim Kardashian. And Jay Z and Kanye are friends.

So it’s little wonder that Beyonce and Kim would hang out from time to time, right?

Beyonce and Kim were snapped hanging out in the crowd of a UK concert while their partners performed the Watch the Thrones show last week – but Beyonce fans aren’t happy about the new friendship.

One tweeted: “Beyoncé and Kim Kardashian in the same picture let alone the same sentence is tragic.”

Another wrote: “if your role model is Kim Kardashian, I can’t take you seriously, Beyoncé is a way better role model. She’s respectful of herself.”

But apparently Kim Kardashian wants the friendship to last.

The New York Daily News reported:

A source tells us the reality star is being extra-careful — and strategic — when it comes to her relationship with the similarly bootylicious pop diva, whose husband, Jay-Z , is touring with Kardashian’s current beau, Kanye West .

Although Kardashian has publicized, marketed and tweeted virtually every aspect of her life (see Ray J sex tape), our source says Kardashian is abiding by the “unwritten rule” that “she is not allowed to blast to the world her business with Bey and Jay,” who are obsessive about their privacy.

“She’s hung with them a few times already, but she isn’t saying peep about them,” says the source.
