The barmaid, who is acting as a surrogate for Gary Windass (Mikey North) and Izzy Armstrong (Cherylee Houston), will give birth to a baby boy called Jake, reports the Daily Star.
As Tina (Michelle Keegan) and baby Jake are forced to stay in hospital due to the premature birth, there is speculation back on the cobbles that Tina and Gary have been having an affair.
In reality, Gary has just developed feelings for Tina since she has been carrying his baby. However, his growing obsession with her has not gone unnoticed by several people, including his partner Izzy.
Michelle Keegan recently confirmed that she is leaving Coronation Street.
The 25-year-old was reportedly keen to leave when her contract expires in November, but show bosses persuaded her to stay another six months to May 2014.
