The Coronation Street star, who has five-year-old daughter Freya with ex-husband Matthew Smith, has revealed she is expecting a baby boy with the 34-year-old former Dancing on Ice star.
She told this week's edition of OK! magazine: 'We actually found out after the 20 week scan but we wanted to wait for a while before we told people.'
Speaking about the baby news, which the couple announced in March, the 32-year-old added:
'I was just over the moon. I feel so lucky that we will have one of each now.
'A lot of people don't have that luxury. If it had been a girl, I would have still felt the same just knowing that everything is alright is the main thing.
'I'm pleased for Sylvain because he's been saying for ages that he's outnumbered with all the girls in his family. It will even up the numbers a bit for him.'
Speaking about the proposal- which the couple announced in May- Samia added:
'I can't believe he proposed to me while we were lying in bed! I was so excited and couldn't think of sleeping.
'I said: "Are you serious?" Then I said: "Do you really want to marry me?!" He said: "Yes, that's why I asked you!"
Congrats guys!
