When you release your very own movie, why wouldn't you want to bring out the exspensive bling? Katy Perry did just that and stepped out on the red carpet wearing over $18,000 worth of TACORI diamonds at the premiere of her new movie, "Katy Perry: Part of Me".

The popstar looked glam in her Diamond Eternity Bracelet (FB1009; $18,370), www.tacori.com, which perfectly complimented her ravishing red strapless gown.

Old Hollywood glamour at its best for sure!
