Hands up if you love her new look?!
The Bodyshockers presenter - who is famed for her pared down (yet totally chic, FYI) style - dialled up the fierce factor and slipped into this Khloe Kardashian-inspired jumpsuit from Rare London, that boasted a dangerously low neckline, billowing cape sleeves and skinny cigarette trousers to boot.
Proving that she can pull off virtually anything, Katie went all out in a pair of bubblegum pink platform heels - Kat Maconie, no less - which featured a chunky gold chain and the highest heel we've ever laid eyes on.
Can we also just take a second to appreciate that co-ordinating lip? SO 80s, we adore!
Amazingly, the gorgeous mum-of-one managed to avoid tripping over as she sauntered down the red carpet and she posed up a storm for the paparazzi before taking to Instagram to tell her fans and followers how excited she was to watch the movie!
"Bit too excited about the fact they Ab Fabbed our seats! #AbFabthemovie," Katie wrote as she shared a picture of her snazzy leopard print chair.
Katie schmoozed with the likes of newly blonde Myleene Klass, Abbey Clancy, Ella Eyre and Kate Moss at the star studded bash but it's safe to say she stole the show.
