Saturdays star Rochelle and her JLS husband Marvin were among the stars who turned up to support Harry Styles, Niall Horan, Liam Payne, Louis Tomlinson and Zayn Malik at the screening of their first-ever film in Leicester Square, London on Tuesday night (20 August).
Rochelle shared her excitement via Twitter en route to the cinema, saying: "Tonight Matthew I'm gonna be....a directioner!"
She was joining thousands of others then, who packed into Leicester Square in the hopes of getting a glimpse of their boyband idols.
Rochelle, who gave birth to daughter Alaia-Mai on 20 May, looked stunning (as always!) in her black floral patterned dress teamed with black heels and a small red bag.
No doubt the beautiful pair met up with Niall inside the cinema to share a few words; just last week the trio were hanging out together at the Humes' house, sparking a rather funny picture of Rochelle and Marvin bottle feeding their 1D pal.
The couple's appearance at the premiere came following a weekend spent at Virgin Media's V Festival in Chelmsford, Essex, where Rochelle and The Saturdays were performing and Marvin turned out to support them.
