Yesterday evening (7 September), Mollie and the rest of her bandmates kicked off their Greatest Hits Live tour, taking to the stage at Glasgow's Clyde Auditorium for the first performance of their 12 dates across the country.
But proving there's no rest for the wicked, the blonde beauty headed straight to London from the far North, only to stop for a short stay before heading back on the road to rejoin the rest of the Sats in Newcastle....
All that, and she still has a smile on her face.
She might have been travelling up and down the country, but proving she is no rookie when it comes to life on the road, Mollie sure looked better than we ever could on-the-go.
About to catch her train back up North after a quick pit-stop in the capital, Mollie looked fresh as a daisy as she posed in her parker coat before climbing on board.
Captioning her pre-train ride snap, Mollie wrote: "4 hours in London, now back up north to Newcastle! Choo choo."
The life of being in a girlband, ey?
Although Mollie didn't reveal the reason behind her swinging by London today, it seems like the star - along with her bandmates - is busy juggling other projects while still strutting her stuff on stage every other night for the next three weeks.
Frankie Bridge will be busy dividing her time between being a Sat and rehearsing for Strictly Come Dancing.
Not only will Frankie have to schedule in learning her lyrics, she will also have to fit in dance practice with her pro partner Kevin Clifton as they are set to perform their first live dance on Strictly in a few weeks time.
And she may not be being thrown around a dance floor, but fellow Sat Una Foden will be feeling a few high kicks in her tummy fairly soon as Una announced she and husband Ben Foden are expecting their second child.
Revealing their baby news on Instagram earlier today, Una decided to come clean on recent speculation and admitted she will be expanding the Foden brood with another tot on the way - and as you can imagine the congratulations came in thick and fast from the rest of her Saturdays bandmates.
Una and Ben are already parents to their two-year-old daughter, Aoife-Belle.
Talk about a band full of multi-taskers....
