Beyoncé beefs up security for London show
Beyonce has increased security at her show in London on Saturday in fear of a British stalker.
The 'Grown Woman' hitmaker is scheduled to perform at the city's Twickenham stadium at the weekend as part of the 'Sound Of Change' concert and staff have been told to look out for prowling fan Bassey Essien, who is reportedly sending her threatening letters labelling her an imposter.
