Yesterday, Katy Perry attended the premiere of her very own film, Part of Me, a documentary that chronicles her life on and off-stage, which is actually out in cinemas next Thursday, excited much? Us to!!

We were even more excited about her choice of arm candy for the event which was held in LA last night. Katy P has been spotted with the odd Judith Leiber number before, but this time she completed her head to toe Dolce and Gabbana look with Judith Leiber's Cake slice crystal minaudiere clutch which has to be one of THE cutest most lust worthy clutches we've seen, pretty much ever.

For those with a spare $4,995 knocking around (any takers check it out here) you can get your hands on Katy's bag pretty sharpish.

You may recognise the style from a scene in the first Sex and the City movie where Charlotte's daughter Lily had the cupcake version at Carrie's wedding (yes, it's sad that we know that). The Sequin Cupcake Clutch Bag is available from Harrods here for £3,950.

There's something about the way Katy is styling out the sparkly number that makes it super cute and quirky, rather than sickly sweet. What do you make of Katy's bag selection for her first film release? Let us know in the comments below!
