The Call The Midwife actress, who has been dating her co-star Jack Ashton for months, looked more beautiful than ever as she stepped out for the lavish affair, in a skin-tight black maxi-dress with a gorgeous slit detail.

But all eyes were on the beautiful blonde’s blossoming baby bump, which she proudly put her hand on as she smiled for the camera.

Call The Midwife’s official Twitter confirmed the news by re-tweeting a post, after the TV Choice Awards wrote: "It's @CallTheMidwife1 with a very pregnant @helen_george plus @charritchie @Jackjashton."

Helen found love with her co-star Jack Ashton following her split from husband Oliver Boot in 2015.

The Strictly star fell for her Call The Midwife co-star off screen, and their romance has gone from strength to strength.

Helen and Jack – who play on-off couple Trixie Franklin and Reverend Tom Hereward in the BBC One drama – are said to have grown close while filming on location in South Africa.

Sources said the actors have been enjoying dates together and booked into an exclusive safari lodge under pseudonyms.

And staff at Moditlo Lodge revealed the pair looked "very much in love".

A manager at the resort, where the couple shared a luxury suite, told the Mirror: "They were here together and seemed very close.

"They spent quite a lot of time by the pool just chilling, doing nothing and being together."
