Pregnant Sophie Cookson who played Christine Keeler in BBC drama is set for her new role as a mother

She played the glamorous model Christine Keeler in a BBC drama about the Profumo affair earlier this year.

But a heavily pregnant Sophie Cookson looked a world away from the character as she stepped out with her boyfriend Stephen Campbell Moore.

The 30-year-old is expecting her first baby with the 40-year-old actor, former husband of The Crown star Claire Foy, 36.

The couple, who have reportedly been dating for 20 months, looked casual as they strolled in north London.

Miss Cookson wore a knitted dress over a black T-shirt and wore little or no make-up with her hair swept back.

The couple met in 2017 while making the film Red Joan, the story of the KGB’s longest-serving British spy.

In the same year Campbell Moore had surgery for a benign brain tumour. In February 2018 he and Miss Foy announced their four-year marriage was over, saying they had been apart for some time.

They have a daughter Ivy Rose, now five. At the end of 2018 History Boys star Campbell Moore and Miss Cookson were pictured together in London, with the actress even wearing his cap.

Miss Cookson impressed viewers as Miss Keeler in the six-part BBC series The Trial Of Christine Keeler, about the 1960s Profumo affair which rocked Harold Macmillan’s government.
