We caught up with Nick and co-star Alex Fletcher, who plays his wife, Diane, to get the gossip on the celebrations and why Nick has stuck around so long.
"I've just enjoyed myself. I've been an actor all my life and the grass ain't always greener," Nick told us. "I've always been happy here, and genuinely still come into work with a smile on my face. But, no, the younger cast members don't ask me for advice. They call me Granddad!"
As well as the ticking time bomb that is Tony's son Harry's secret relationship with Tony's best mate Ste, there's romance in store for Tony and Diane when the couple decide to renew their wedding vows, which sees the return of former co-star, James Redmond, as Tony's buddy, Finn.
"It'll be nice for Diane to have a bit of happiness because she cries all the time!" says Alex.
