Katherine Kelly has revealed that she is expecting her first child.

The former Coronation Street actress announced on Twitter that she and her new husband Ryan Clark were to become parents.

She wrote: "Ryan & I are overjoyed to announce that we are expecting a baby! Feeling very blessed!"

The baby news comes less than a month after Katherine and Australian Ryan, both 33, jetted to Las Vegas to tie the knot.

Friends have been congratulating Mr Selfridge actress Katherine following the announcement, including EastEnders' Jo Joyner.

She tweeted: "Congratulations! Didn't take long! It's going to be fantastic, enjoy every second xx."

Katherine and Ryan have been together for around three years. The couple married at the Little Church Of The West in Sin City in August.

The star told Hello! magazine after her nuptials: "I love going to other people's weddings but I have never desired a big white wedding for myself and it has never been put on me as a pressure, an expectation."
