Tina's first appearance on the StreetTina McIntyre debuted on Corrie in 2007 by immediately getting into an argument with her future stepmother Gail Platt over a missed doctor's appointment.Viewers were immediately introduced to Tina's "gobby" attitude and Gail's dislike for the young girl, who would eventually become her son's girlfriend."I was so embarrassed," said Michelle. "I remember thinking: "I hope they don't think I'm like this in real life" because I wasn't used to it all."Tina comes clean in courtTina is giving evidence against Gary Windass who is accused of assaulting her then boyfriend David Platt.But she is unable to lie in court...Michelle said: "In the end Tina showed her true colours by not being able to lie, because she hasgot good morals."I just like this clip because it was the first time I had ever been in court, it was a lot of pressure, I loved it and we had a great time away for a week - all of us had a great laugh."Tina's dad Joe is found deadMichelle Keegan stretches her acting muscles in her third favourite moment when David arrives to tell Tina that a body has been found and it is her dad Joe."This one of my favourite storylines that I have ever had to do on Coronation Street, because it was emotional, it was difficult but I loved the journey that Tina had to go on," said Michelle.Terry attacks TinaDuring Tina's relationship with Tommy Duckworth, his no-good dad Terry made a reappearance and soon got the pair embroiled in debt with drug dealers.During one scene Tina and Terry have a scuffle and Tina is left unconscious."For this clip I had to do a stunt where I had to whack my head on the floor and go unconscious," explains Michelle."It took a few times to do and I did end up with a headache, but looking back at the clip it was worth it."Tina gives birth to baby JakeIn 2012 Tina agreed to be a surrogate mother for Gary and Izzy Windass and gave birth to baby Jake in May last year.What followed was an emotional time for Tina, but the birth scene is one actress Michelle is most proud of."This was probably one of the most nerve-wracking scenes for me because obviously it's very technical," she said."You have to get it right, you have to make it look real and I wanted it to look the best it possibly could."I watched a lot of One Born Every Minute to try and get it right. I remember screaming a lot that day, I remember my voice was going, I remember through all the pretend breathing I lost a lot of oxygen to the brain and felt a bit dizzy."But I've watched it back and I'm quite proud of it.
