London, November 12 British singer Leona Lewis has showed the hand to the idea of hiring giant bodyguards despite a recent attack by a crazed fan.

The former X-Factor winner was punched in the head at a book signing in London on October 14. The man accused of leaving her badly bruised was said to be suffering from paranoia and delusions of grandeur.

But the 24-year-old refused to step up her security, saying the assault was a one-off, reports the Mirror.

She said: "I had a little bit of time out immediately after [the attack], time to be with my family and a chance to get over the shock. Now I'm just kind of dealing with it and trying to put it behind me.

"As for extra security - well, I've tried to keep it pretty much the same. I've always tried to keep as few people around me as possible because I don't feel like I need it.

"But now, after this, I also know that doing this you have to protect yourself a little bit. Being in this industry you are exposed - more so than other people. I know that I have to look after myself as well."

She added: "I won't be doing a Beyonce and employing a 7ft bodyguard, although it seems to work for her!" (ANI)
