Helen Flanagan, who plays the flirtatious character, is currently on a three-month break from the ITV1 soap after asking for time off to spend with her footballer boyfriend Scott Sinclair.
Rosie will be back to her outrageous ways when she makes her comeback as a new plot sees her strip down to her underwear in a bid to seduce her mother Sally's boyfriend Jeff Cullen, according to The Sun.
Jeff, played by Steven Houghton, was first introduced to the soap in February. As well as dating Sally (Sally Dynevor), he has worked as Rosie's manager under the alias 'Alfie'.
Coronation Street fans will reportedly see Rosie and Jeff's racy scene in September.
During her time away from Weatherfield, Flanagan has unveiled a short blonde hairstyle. However, she is expected to go back to normal in time for her return to filming next month.
