Is There a Feud Brewing Between Beyoncé and Kim Kardashian?

While all seems blissful between lovebirds Kanye West and Kim Kardashian, a third diva in the picture — Beyoncé — might be a raincloud they never saw coming.

While Jay-Z and Kanye travel all over Europe together this spring and summer for the Watch the Throne tour (They'll globe-trot through Germany, Paris, Ireland and England.), Jay's wife is grumbling under her breath about Kanye's new girlfriend.

"Beyonce’s not happy about Kanye’s relationship with Kim," a source told The Sun. "She had a conservative upbringing which was very different to Kim’s. Bey’s never been impressed by Kim's record with men and the sex tape that leaked a few years ago. Her 72-day marriage doesn’t exactly inspire her with confidence that Kim wants the relationship with Kanye to last either."

Very interesting — but doesn't Beyonce have better things to do than grumble about Kim and Kanye? And doesn't Kanye have just as much to prove on the relationships front as Kim?
