Gaga boosts security amid fears over fan obsessions

Lady Gaga makes her bodyguard watch over her while she sleeps.

The ‘Poker Face’ hitmaker is said to be terrified of being murdered by a crazed fan in a similar way to Beatles legend John Lennon – who was shot dead on the steps of his apartment building in 1980 - and has boosted security to be with her at all times, even moving some staff into her New York apartment.
