The 31-year-old star - who portrays money-grabbing mother-of-one Cindy Hutchinson in the Channel 4 soap - has announced she is already past the first trimester and can't wait to welcome her second child into the world in the summer.
Speaking about being a mother to her four-year-old daughter Mia, Stephanie revealed: "I've got one on the way as well!"
I've got one on the way as well!
The actress has had a terrible time filming 'Hollyoaks' recently whilst she struggles to control her hormones - which have been haywire since she conceived - and her emotional storyline.
Cindy is faced with every mother's worst nightmare when her daughter Holly (Lydia Waters) goes missing.
However, Stephanie is convinced her news has helped her with the tearful scenes.
She told Channel 5's 'Live at Studio Five': "That's how I think I've managed to do all the crying scenes because I've been so hormonal!
"I'm already at 12 weeks - I've just had my scan so I'm quite happy to say it and I thought I'd take the opportunity while I'm on here. I'm so excited."
Stephanie also revealed her young daughter is desperate for a baby brother, while she wants the newborn's sex to be a surprise.
