EastEnders has confirmed that Martin Fowler is to receive big news from Sharon Watts, in new advanced spoilers.
In September, Sharon spent a week in prison, where she was reunited with her former stepmother Chrissie.
After a dramatic few days, the pair eventually made amends, and Chrissie revealed that she once shared a cell with Ruby Allen - who then left to have a baby.

Sharon was shocked when she realised that this meant Ruby was telling the truth about her pregnancy and Martin had a child who he didn't know about.
Once back in Walford, Sharon prepared to tell Martin the news, but he was already stressed about Sonia's imprisonment, so she kept the secret to herself.
However, in new spoilers released by the BBC, Sharon has some "big news" for Martin later this month, teasing that she might finally choose to spill the beans about the baby.
With Louisa Lytton confirmed to be reprising her role as Ruby this autumn, how will Martin react to Sharon's news?
