Shame on us.
Frankie, who is currently on the road with her dance partner Kevin Clifton for the Strictly Come Dancing Live Tour, upped her hair game last summer when she switched up her trademark short hair for a sexy, shoulder-length do at Kennadys Salon in Ingatestone, Essex.
And there we were busily enjoying her bob and not really paying attention, when on Tuesday (23 February), we noticed The Saturdays lady's hair looked remarkably longer all of a sudden.
We can only apologise for missing such hair news, because after trawling through Frankie's Instagram feed, we realised she got new extensions... OVER. A. WEEK. AGO.
Frankie's latest hair makeover came thanks to the expert extensions team at Inanch London, on Great Portland Street in the capital's West End.
Fellow bandmate, Rochelle Humes is a big fan of the hair hot-spot, as are Michelle Heaton, TOWIE lady Billie Faiers and The O.C.'s Mischa Barton.
Frankie's new do is a great length on her and it's nice to see she hasn't gone too crazy-long. In fact, with plenty of layers around her face it looks natural, full and pretty darn gorgeous.
So, is this extension journey going to carry on, we wonder?
If so, we predict her locks will be down to her bum by Christmas!
Maybe not, then...
