Described as "hardworking", she is heavily protective over her family and makes enemies such as Pauline Fowler (Wendy Richard) and Stacey Slater (Lacey Turner).
Rosie was married to Mike Swann (Mark Wingett), and they had two children, Mickey and Dawn (Joe Swash and Kara Tointon).
Rosie later met Keith Miller (David Spinx), who took on her children as his own before having twins, Darren and Demi (Charlie G. Hawkins and Shana Swash).
She has a number of cleaning jobs, and takes care of her granddaughter, Aleesha (Freya and Phoebe Coltman-West), while Demi and Darren go to school.
Annoyed, Rosie jilts Keith during the ceremony and tells him the next day that she no longer loves him and plans to take a job in the Cotswolds.
On 9 December 2024, Mickey makes a brief return to Albert Square and reveals to Big Mo that Rosie is working at his new family business, ‘Miller’s Villas’ alongside his sister Dawn.
Louise Berridge, the executive producer, commented: "I'm delighted to introduce the Miller family, who will be joining Mickey on Albert Square in September, but I warn you - this lot are trouble".
