"Thrilled to say my show that I co wrote Sex and the Suburbs has opened to rave reviews,but the BEST news is I'm 5 months pregnant!!" she tweeted.
Claire, 43, and computer software tycoon Daniel split in December, however they only announced it last month. The pair remain close and are both excited about their impending arrival.
Following her announcement, Claire's rep added: "Claire could not be happier. To be pregnant and starring in her own show in her home town of Liverpool is all her dreams come true at once."
Claire's pregnancy has come as doubly happy news for the former couple, as she sadly suffered a miscarriage in 2012. At the time, Claire said she was philosophical about it, adding: "It wasn't meant to be."
