The former Coronation Street actress surprised everyone with her lovely baby news, just by showing off her growing tummy.
Even though she didn't need to say it, Suranne confirmed the news at the red carpet of the NTAs, saying: 'Yeah, I'm pregnant!'
Dressed in a beautiful one-shoulder black dress, she also said she and her husband were skipping an antenatal class to be at the ceremony.
Judging by the size of her bump, she's been keeping the pregnancy a secret for a good few months.

The night just kept getting better for Suranne, as she won the Best Drama Performance award for her role as Doctor Gemma Foster in the hit BBC show.
The series, which they will start filming again in September for the second series, also got the award for Best New Drama.
Accepting the award, the mum-to-be said on stage: 'Thank you for voting for us, we start filming the new series in September so we look forward to you seeing that, have a great night.'
This will be the first try at motherhood for the Doctor Foster star and her husband, magazine editor Laurence Akers. The two tied the knot in August last year, in a private ceremony in London, with only a few witnesses present.
Suranne met Laurence in 2014, and the pair got engaged after only six weeks of being an item.
And from an interview she did shortly before getting engaged, we know their romance must be really special.

Declaring she was still single at the time, Suranne said: 'Once you have your own life, your partner has to be someone very special because life is so busy. If that person isn't right for you, don't settle for second best.'
Before meeting Laurence, the Corrie star dated half-Italian plumber Lorenzo Giove for three years, and fellow actors Jonathan Wrather, from Coronation Street, and Marc Bannerman, best known for his role as Gianni Di Marco in EastEnders.
Congratulations to the couple on their lovely news!
