Out in the capital, Frankie couldn't resist flashing her pearly whites as she left the BBC studios earlier today.
And, so she should, as she deservedly bagged herself a place in Strictly's final four alongside Caroline Flack, Simon Webbe and Mark Wright during last night's results show - congrats!
With her dance partner Kevin Clifton closely behind her, Frankie looked super stylish as she appeared on Chris Evan's BBC Radio 2 show this morning.
Dressed casually, the 25-year-old wore a pair of black skinny jeans and a khaki green knit on top, sassing up her ensemble with a very cool pair of leather strapped boots.
But, despite a busy week of rehearsals looming, Frankie didn't seem to mind too much. Clearly still on cloud nine from making the Strictly final, the singer flashed a big smile as she made her way past waiting photographers.
Over the weekend, Frankie joined her Strictly Come Dancing co-stars to perform two dances for the show's semi-final. And, after a strong performance on both occasions, the mum-of-one found herself sitting second on the leaderboard.
Having been consistent throughout the competition, it's no surprise Frankie escaped the bottom two, edging one step closer to getting her hands on this year's Mirrorball trophy.
But, while she'll be perfecting her dance moves for the last time, EastEnders star Jake Wood just narrowly missed out on holding onto his dancing shoes - despite being a favourite to win the show.
Finding himself in the bottom two, Jake was sent home from Strictly after Mark Wright was saved by Len Goodman, surviving yet another dance off.
Following his exit, Jake took the opportunity to thank his dance partner Janette Manrara.
He said: "It's a huge disappointment to go out at the semi-finals, but for a 42-year-old dad of two, I've never danced before, I've never had a dance lesson - this woman has worked wonders."
Meanwhile, Caroline has been dubbed as the new favourite to win this year's Strictly contest after her faultless performance on Saturday.
The TV presenter scored tens across the board for her Salsa, with Len telling Caroline if she didn't make the final, the "world has gone mad".
Good job she did then, right Len?!
The Strictly Come Dancing final begins this Saturday 20 December at 6.30pm on BBC One.
