EastEnders actress Jacqueline Jossa has revealed that she and her co-star boyfriend Tony Discipline had a Harry Potter-themed celebration for their first anniversary.

The pair, who play Lauren Branning and Tyler Moon, have been dating for a year, and Jacqueline told Inside Soap magazine that the date was an ideal way to indulge their love of JK Rowling’s hero.

“A couple of weeks ago we celebrated our one-year anniversary. We went on the Harry Potter set tour,” she said.

“I’m such a big fan of the films, and I got Tony into them recently – we watched the whole lot in about three days. It was amazing!”

Although the pair may be together in real life, Jacqueline added that they see very little of each other on set since their characters move in different circles – with Lauren about to find love with her cousin Joey Branning, played by David Witts.

“It’s funny because Tyler and Lauren never speak! But it’s nice because we can tell each other about our days when we get home,” she revealed.

And she also responded to the recent rumours that Lauren may in fact be Derek’s secret love child – which would make her Joey’s sister rather than cousin.

“I have heard this rumour – and it’s crazy!” Jacqueline admitted. “I actually think it would be a good twist, although Joey and Lauren’s romance would definitely be forbidden if they were half brother and sister.

“I doubt that’s the case – but this is EastEnders – so who knows?!”
