Imogen Thomas is expecting a second child with her boyfriend Adam Horsley.

The 32-year-old star - who is a former contestant on 'Big Brother' - shared her joy she is becoming a mother again on Twitter, where she posted a photo of her and two-year-old daughter Ariana with her scan photo.

Confirming her pregnancy, the accompanying tweet read: ''I'm going to pop! This little Madam can't wait 2 be a big sister in Nov! She's going to be the best #novemberbaby (sic)''

It's no surprise Imogen and Adam are expanding their family as back in December 2014, she revealed to New! magazine her New Year's Resolution was to become pregnant again.

She said: ''If things go to plan it will happen quickly. I really want Ariana to have a sibling because I had my sister around me. I know she's going to love it, she loves babies.''

Imogen was flooded with congratulatory tweets, and surprised by the response she got from her friends and followers.

She responded with a tweet, which read: ''WOW! Thank you so much to all you wonderful people for the congrats. I'm an emotional wreck with all your lovely messages (sic)''
