Mollie King, Vanessa White, Una Foden (nee Healy), Rochelle Humes and Frankie Sandford seemed to be sharing a joke – or poking fun at Rochelle? – in a photo posted to Instagram by Frankie.
She added the caption: "We take our job very seriously."
We can see!
As always, the five singers looked ridiculously glossy and groomed for their day of filming a special for MTV.
Mollie, Vanessa, Una and Rochelle all flashed a little tummy in summery crop tops, while Frankie oozed chic in a monochrome shirt.
It feels like it's been a while since we saw The Saturdays together en masse, although we've seen plenty of them out and about individually.
Una kicked off the year appearing on Tom Daley's diving show Splash!, while Rochelle has been focusing on TV work with Sweat The Small Stuff and guest hosting stints on This Morning.
Frankie, meanwhile, has been focusing on life as a mum to baby son Parker Bridge, who was born in October 2013.
It's good to see them all back together!
