Coronation Street's Robert Preston tipped for surprise baby storyline with Kate and Rana

Coronation Street could see a surprising baby storyline for Robert Preston as he considers being a sperm donor for Kate Connor and Rana Nazir.

Rumours suggest that Robert (Tristan Gemmill) is approached by the couple (Faye Brookes and Bhavna Limbachia) after he's left upset by the fact that Michelle Connor (Kym Marsh) doesn't want any more children.

Kate and Rana want a child of their own and try to convince Robert to be their donor. Robert is said to agree on the condition that he gets to remain anonymous, reports The Sun.

It's unclear at this stage whether or not Robert, Kate, and Rana go through with this plan, though we're pretty excited to find out.

Next week will see Kate and Rana's proposal storyline kick off, as Kate makes romantic plans for when Rana returns from her six-week cruise.

Rana has been away with her mother, but recently-released spoilers indicate that they will eventually become engaged.

However, their engagement hits a roadblock as they appear to have different ideas for the future.

"Rana and Kate have been through so much and faced so many hurdles already that I hope the end goal to be together can be realised," said Limbachia, who plays Rana.

"They've fought this far, so I think they'll be willing to fight all the way."
