Jane posted a picture with the fellow actress, who plays Shona Ramsey, to her Instagram account.
She captioned the post: "Happy maternity leave beautiful @julia_goulding. I'm so excited for you. Enjoy this special time. Happiest days."
Julia commented on the picture saying: "Awww thanks, love you Jane! Thanks for looking after me in the lead up."
Co-stars and friends rushed to comment.
Georgia Taylor, who plays Leanne's sister Toyah Battersby, wrote: "Oh what a gorgeous pic of you two lovelies."
One fan commented: "Take care and enjoy your new little one. Hope to see you back on the cobbles again soon."
A second said: "Good luck Julia. Will miss you in Corrie."
Julia also posted pictures to her own Instagram Stories pictures of the gorgeous flowers her Platt family cast members bought her.
Julia announced she was expecting her first child with husband Ben Silver back in May.
Her alter ego Shona recently wed David Platt.
The big day almost didn't go ahead as David was falsely accused of attacking his rapist, Josh Tucker, in prison, and was remanded in custody.
Happy maternity leave beautiful.
After car troubles, Nick managed to get his brother to the Bistro where the wedding took place.
The wedding went smoothly, leaving viewers wondering what will happen to Shona as Julia goes on maternity leave.
After the wedding, David was told the Crown Prosecution Service was resurrecting his rape allegation against Josh.
Could this have something to do with Shona's exit, or will it be completely unrelated?
Coronation Street is on Monday and Wednesday at 7.30pm and 8.30pm, with an hour-long special on Friday at 7.30pm.
