Who's your daddy?

For the biggest stars, it is simply this season's must-have fashion accessory.

As Beyonce Knowles proves on a Beverly Hills shopping trip, the true measure of celebrity stature is now judged by the size of the hired muscle. And bodyguards don't come any bigger than this.

In a classic case of one-upmanship, the Crazy In Love singer has employed a man-mountain on an even grander scale than those seen recently towering over Justin Timberlake, Christina Aguilera and Britney Spears, who took her 25-stone bodyguard Big Rob on holiday with her last year.

Not only does Beyonce's new man ward off over-eager fans, he's perfect for carrying that heavy water bottle.
