Beyonce and Kim Kardashian hang out at Kanye and Jay-Z concert

It was only a matter of time given the close friendship between their men, and while that whole 'our partners are friends so now we have to be too' thing can be so awkward, it looks like the two actually had a good time laughing and dancing as Jay-Z and Kanye performed.

"Kim and Beyonce were dancing all night! They even went into the mosh pit!" a fan in the crowd told Us Weekly. "It was the most hectic thing ever!"

Pics posted on Twitter show Beyonce, 30, and Kim, 31, trying to hide their faces from a sneaky snapper as they enjoyed the concert.

Since the long-held rumour goes that Beyonce isn’t exactly Kim's biggest fan, Kanye organised a pre-concert dinner date so the two could get to know each other better, according to the UK's The Sun newspaper.

If Beyonce isn't sold on Kim yet, she might as well get used to her being around, if the way Kim gushed about Kanye in her recent interview with Oprah Winfrey on US program Next Chapter is anything to go by.

"It's very comforting to have someone that knows everything about you, that respects you, understands, has gone through the similar things," Kardashian said.

"There's so many similarities in our life that ... I feel like I'm at a really happy, good space."

Will we see Beyonce and Jay-Z on an episode of Keeping Up With The Kardashians, as previously reported? Watch this space (as well as the Throne).
