Cat Deeley and Patrick Kielty have been friends for 10 years
PatCat made their official red carpet debut as they cuddled up at the Glamour Women Of The Year awards last week - but are they secretly engaged?

Cat Deeley, 35, was snapped wearing a thin gold band on her engagement finger as she left the event with Patrick Kielty, 41.

The pair, who'd been friends for 10 years before they started dating this January, had earlier looked completely smitten.

A source says: '[Patrick] was giving her affectionate kisses and had his arm draped protectively around her chair. 

'It was clear this was their "coming out" as a couple and he was keen to show his love for her.'
