Katy Perry's Cleavage Steals Show At Her Perfume Launch

London: Pop singer Katy Perry gave onlookers an eyeful of her cleavage at the launch of her fragrance 'Purr by Katy Perry' in Mexico City.

The 'California Gurl' singer poured herself into the incredibly low-cut frock at the party, reports the Daily Mail.

There was only a thin piece of sheer mesh holding the plunging neckline together.

But the purple shade matched the colour theme of her latest business venture and the dress was emblazoned with sparkly diamantes.
