Tina split from Tommy (Chris Fountain) a few weeks ago following weeks of rows over her surrogacy plan, but they have recently got back on friendly terms amid their shared concern for Tyrone Dobbs (Alan Halsall).
Watch our interview with Michelle Keegan in the video below:
Keegan told Digital Spy: "I love Tommy and Tina together. They are friends at the minute because they're looking after Tyrone, but who knows?
"At the minute, I'm looking at the scripts and they're not together, and I haven't heard they're getting back together, but I hope they will do. They're a great couple."
Asked whether she would like the pair to have a child of their own once Tina has given birth to Gary and Izzy's baby, the actress replied: "I think they're too young. They moved in after a month of being with each other, but that's what happens in soap.
"I think they're too young at the minute and they need to enjoy being a couple, because as soon as Tina and Tommy got together, there was all that drama of Tommy's dad coming in, the debt and the loan shark.
"That's when they split up, so I do think they need time to just be a couple and be happy."
