The Saturdays have helped launch this year's Poppy Appeal.
The event featured video messages from personnel stationed in Afghanistan for the families of those watching.
Mollie broke the news via Twitter 'So excited to be the faces of the poppy appeal! It's such an honour! Hope u guys can all support too! Xx'
The launch also featured a parachute display from the Royal British Legion's extreme human flight team, 'Jump4Heroes', who landed next to the site where the first new Personnel Recovery Centre will be built; they've committed £25 million to the Personnel Recovery Centres.
The Royal British Legion is the nation's leading Armed Forces charity providing care and support to all members of the British Armed Forces past and present and their families.
Earlier this week The Saturdays were unveiled as part of this year's Jingle Bell Ball line up.
