Rumours recently suggested the Sing star had landed a cameo appearance in the third installment of the romantic comedy franchise, Bridget Jones's Baby, and he has now addressed the speculation by sharing a photograph from his acting stint.

Ed posted a picture on his page, showing him snapping a 'selfie' photo with the film's star Renee Zellweger during a scene in a bar.

"Spent the day being an actor in the new Bridget Jones movie. Loved it, you're gonna love it too... #bridgetjones and #bridgetjonesbaby," he wrote.

Filming on the third movie, which reunites Renee with her former co-star Colin Firth, began in July (15) with scenes filmed during Ed's gig at Croke Park stadium in Dublin, Ireland.

Renee's body double was spotted in the crowd at the show, sitting on the shoulders of a mystery man.

The long-delayed film has been in the works since 2011, but the project hit a number of delays due to problems with the script, and British actress Emma Thompson was drafted in to rework the screenplay.

The third film follows 2001 comedy Bridget Jones's Diary and its 2004 sequel Bridget Jones: The Edge of Reason, both based on the works of British author Helen Fielding.
