The 39 year old made the announcement to her 70,000 Twitter followers on Thursday afternoon, with the tweet; 'Shhh... don't tell anyone, but I'm pregnant! My hubby and I are over the moon and looking forward to meeting our little person in November.'
Danny Dyer was one of the first to wish Kelly well on Twitter, saying, 'Just when I thought I couldn't get any happier. x' While Kelly responded by thanking Danny for 'being my friend'.
The cheeky chap then posted a funny snap of a lost-looking kitten along with the caption, 'Me in the vic on my jack when @kelliebright76 is on maternity leave. #lost'
Producer Dominic Treadwell Collins also sent his congratulations, saying: 'We can finally talk about it!!! So happy for you and Mr Stocker. #NoMoreLycraForLinda.

The Strictly Come Dancing contestant, who will be 40 years old when she gives birth to her child, is expecting just before Christmas.
It is the second child for Kellie and her husband Paul Stocker, who already have a son Freddy, born in December 2011. We don't expect to see much of their second child as the couple have been keen to keep Freddy strictly out of the limelight.
The actress has already confirmed to her BBC soap fans that she will be returning to her on-screen husband Danny Dyer after having the baby with the hashtag #queenvicismyhome.
Kellie also appeared in the 13th series of Strictly Come Dancing with partner Kevin Clifton, and they reached the final three before being voted out by the public.
The actress married Paul in July 2014 in a romantic countryside venue in Cornwall, with friends and family. She previously dated actor Ross McCall who she had known since she was 11 years old.
Kellie has previously made appearances in Sacha Baron Cohen's Ali G Indahouse, Kinky Boots, Bad Girls, Silent Witness and The Catherine Tate show.
Fans have rushed to congratulate the actress on her happy news, with Emma Lowman saying: 'Omg I am screaming so so happy for you guys! Congratulations beautiful. I'm feeling so emotional.'
Ashley said: 'Wow! Someone is going to be busy! Best wishes and congrats coming your way!'
