The Saturdays' Rochelle Interviews Mollie
I decided to give Mollie a grilling about public transport and what she loves about being a Saturday.
Find out what Mollie had to say in my interview, and make sure you send all of us your questions for the live chat on the website tonight from 7pm.
Oh, and don't forget our new single 'All Fired Up' is out now!
