UH OH. Beyonce’s craziest fans are called The Bey Hive, but it looks like they are just getting out of control. Just recently, a dude slapped B on her butt. But, these people are acting a fool. One person – clearly insane – claimed that Beyonce had been murdered and replaced by this “imposter.”

The UK Sun reports the drama:

SUPERSTAR Beyoncé is stepping up security at her Twickenham stadium gig — amid fears of a British stalker.

Staff have been told to watch out for obsessed fan Bassey Essien when the Crazy In Love singer headlines the Sound Of Change concert on Saturday.

It is believed she has been sent sick threatening letters.

Essien has already been warned to stay away from Beyoncé, 31 — who won an anti-harassment order in the High Court in 2011, prohibiting him from pestering her.

Court papers revealed Essien, of South West London, had been sending threatening letters to the star since 2009 and made a bizarre claim she was an imposter who had killed the real Beyoncé.

A source said last night: “Staff have been briefed on the situation and pictures of him have been passed round. They’ve been told to keep their eyes open and be extra vigilant.”
The source also revealed: “Security has been increased on a few engagements now, especially for her UK promo.

“It is believed similar letters to the ones that Essien sent have been received.”
