Who's my famous sister?Who's my famous sister?Well, you could knock us over with a showbiz feather.

This serene young lady looks nothing like her risque sibling.

The lady was spotted with her famous relative doing a spot of shopping on Rodeo Drive in Beverly Hills.

But what had us slobbering with surprise was the chalk-and-cheese difference that separates the two sisters.

Of course, this senorita has the same raven hair and waxy pallor as her sibling.

But as far as style is concerned (one of the famous sister's trademarks, btw), they're football pitches apart.

This lady has apparently inherited none of the penchant for quirky feathers and fabulousness that defines her legendary sister.

Instead she makes use of an accessory that has about as much sex appeal as a wet fish - an Alice band, no less.

And though her top is fairly low-cut, it could be classed as conservative next to her sis' vampant showcase clobber.
