Jamie, 26, is set to star as coach Joe in the musical for the next six months, which follows the story of a soccer-loving girl in London.
Lily has been documenting her trip to London to attend the premiere on her Instagram, posting cute snaps with Jamie as they travel around the city.
“Let the bending begin!! Its about to get wild!! Couldn’t be prouder #openingnight #benditlikebeckham…,” the starlet captioned the photo.
Jamie also took to his Twitter to share a photo of the couple at the premiere saying, “A special night made 10 x more so by having this lovely by my side.”
FYI: Lily is wearing an Ella Moss skirt in her Instagram pic. She is wearing a Maje dress to the premiere.
