The pair were reunited last year as part of a dramatic Christmas storyline.

Previously speaking on Lorraine, Jeff confirmed that he went to school with William.
He explained: “We did a play together at school yeah.”
The pair both attended North Chadderton School in Oldham in their younger days.
Jeff is not the only person William knew before joining the cast of Emmerdale.
The actor previously said: “I’ve met a lot of the actors who play those roles before.
“I knew Lisa Riley from Oldham Theatre Workshop, so it was less daunting having known those people than if I didn’t know anybody.
“Lucy Pargeter, too, I worked with her a long time ago as well.
“So the people I was working with I had a bit of a relationship with so I wasn’t as scared as probably I should have been.”
Will kicked off his career alongside Robson Green in hit ITV drama Soldier Soldier back in 1997.
After this he landed a plum job on Where the Heart Is followed by Clocking Off and then Waterloo Road.
On the big screen, he’s starred in Mad About Mambo and Hush.
After making minor appearances in rival ITV soap opera Coronation Street, Jeff was cast as Cain in Emmerdale in 2000.
