Meanwhile, Sheridan previously revealed she wants to give her son a ''traditional'' name.

Speaking about the options for the kid's moniker, she said: ''We've been discussing names. I think all the names we've got so far have been pretty traditional. We thought about naming him after my dad, but my dad's called Colin, which is a bit ... Well, as much as we miss him and love him, it's like, 'Storm, River ... Colin?!' But you never know.''

The 'Cleaning Up' star had previously insisted she was having an ''easy ride'' with her pregnancy, and says that even at seven months she isn't suffering from any cravings.

She added: ''I'm feeling really good. I haven't had any pregnancy cravings yet. I've had quite an easy ride. I had a bit of morning sickness in the beginning, but I've been quite lucky ... Honestly, Jamie has been looking after me so well - he's the best. He does everything while I'm just sat at home with the dogs and baking a baby. I've got an easy life!''
