Filming for Netflix's new musical comedy is now underway.
And Will Ferrell was seen leaving the set of his new film in London on Tuesday, and the 52-year-old actor was joined by singer Demi Lovato.
While the singer, 27, has not officially joined the cast, she spent some time on set as she was seen arriving at the venue while the shoot took place.

Demi put on a casually chic display as she stepped out for the day's shoot, as she donned a tie-dye jacket, which she wore over black leggings.
She completed her ensemble by stepping out in Givenchy slippers, while she tried to keep a low profile by covering her raven locks with a black baseball cap.
After spending some time on set, Demi rang in her 27th birthday alongside manager Scooter Braun and labelmate Ariana Grande.
Meanwhile, Will looked relaxed in a black T-Shirt that he teamed up with beige trousers and blue suede shoes.
