Cat Deeley is pregnant.

The 'So You Think You Can Dance' presenter and husband Patrick Kielty - who she married in a secret ceremony in Rome, Italy, in 2012 - are ''so happy'' to be expecting their first child together.

Cat revealed on Twitter: ''Exciting news... Paddy and I are so happy to be expecting our first child in the spring... Lucky us.''

The news comes just a month after the Northern Irish presenter joked about the possibility of having children with his 38-year-old wife.

He said: ''I hope any child we might have has Cat's looks and my accent.

''With our two strong accents, we basically needed subtitles or a UN translator.''

The couple were friends for 10 years before they tied the knot and the 44-year-old star recently insisted there was ''always a spark'' between them before their relationship became romantic.

Patrick said: ''There was always a little bit of a spark between us but either she was with someone or I was with someone and by the time we were both single she was in America. It was always one of those things that never worked out.

''Women tend to be in charge and we men just have to get on the pitch, stand on the leg that's shaking most and not drop the ball when it comes our way.''
