Kelly, who is expecting her baby girl in the summer, looked fit to burst with pride as she sauntered through central London in a pretty beige and brown ditsy print dress with a side frill, and a cute mink-coloured cardie.
Her frock barely skimmed her tanned thighs, but all eyes were on her growing bump, as she and Thom strolled through the capital.
Kelly's maternity outfit was topped off with brown gladiator sandals and a tan leather bag, whilst dad-to-be Thom rocked a preppy look in a pale blue jumper and dark indigo jeans.
Given her parentage, we reckon their new daughter is going to be one gorgeous and stylish tot - move over Suri Cruise!
