The Saturdays star was pictured outside Claridge's Hotel in London on Wednesday (17 June), the morning after helping best friend Georgina walk down the aisle.
Rochelle was looking fresh-faced and gorgeous in a white striped dress and sandals, as she walked arm in arm with Marvin.
The 'What About Us' star was one of seven bridesmaids who supported ex-reality star Georgina as she tied the knot with Manchester United and England footballer Tom Cleverley.
Among the guests at the lavish reception were Coleen and Wayne Rooney, who had also been pictured leaving Claridge's earlier in the day.
Rochelle and Georgina have been friends for years. It was actually Rochelle who broke the news Georgina was engaged by sending an excited tweet of congratulations for her "bestie" last year!
Rochelle was on hand to help property developer Georgina celebrate her hen do in May, and the girls' young daughters Alaia-Mai and Nevaeh are known to be playmates.
