The show's boss confirmed that he is keen to keep developing Rita's close bond with Dennis Tanner, who returned to the cobbles earlier this year.
Collinson told Inside Soap: "Rita genuinely loves Dennis very much. Their storyline harks back to 1964, when he looked after her and took her in. Now he's grown to love her because she's been able to look after him.
"I like that we can tell a love story of people in their 70s, and it's a relationship that we're really committed to. I'd love for Rita to have a wedding, so watch this space! And if we did have one, she'd be Mrs Tanner - how great is that?"
Speaking last week, Lowrie commented: "I'm having the best time of my life. I live in London, but now I work here in Manchester for a few days a week, so I have the best of both worlds.
"At my time of life, to have a job that I love so much and getting to play such an amazing part, is fantastic. I can't believe my luck, to be quite frank with you."
This week's Coronation Street episodes see Rita trying to support Dennis following the arrival of Norma, a face from his past.
