Deeley, 35, who hosts “The Choice”, met the Irish comedian in 2002.
Sources report the couple held an engagement party for family and friends at The Goring Hotel in London, where Cat showed off her engagement ring.
A source revealed, “Cat and Patrick have been friends for years, so even though they’ve only been dating a few months, they know they’ve found The One in each other. They wanted all their friends to know they were engaged straight away”.
Patrick, 41, moved into Cat’s Beverly Hills home in May after the couple were spotted together for the first time in February.
