Katie left the gym in her sporty ensemble - a rather stylish zip up jacket, long tee and plain leggings - and headed to Teuscher Chocolates for a quick cuppa and some luxury sweets.

Oh, and matching your shopping bag to your trainers? That's fashionista commitment.
What do you think of Katie's look? Let us know in the comments.
