Selena Gomez was spotted running onto the streets in New York in a wedding dress as she filmed scenes for Only Murders in the Building season three.
The actress, 30, plays Mabel Mora in the show, and was seen with her co-stars Steve Martin and Martin Short.
She wore a huge princess-style wedding dress in pictures and video taken on Tuesday in Manhattan, which shows the trio jumping into a yellow cab.
An onlooker said: "Who'd have thought it - Selena Gomez in a wedding dress.
"It was very surreal.
"The streets were mad with traffic and cabbies and everyone jockeying for position.
"It was frantic with people, then suddenly everything went silent, like everyone instinctively knew."
In the show, the trio use true crime knowledge to investigate a gruesome death in their posh upper West Side apartment block.
The by-stander said he saw them filming scenes exiting the building they use for exterior shots, at around 6pm, off Broadway.
