The Saturdays singer pulled off yet another chic off-duty ensemble, sporting a crisp white T-shirt with rolled-up sleeves.
She tucked her tee into her skinnies and added a boyish vibe with brown leather brogues and a gold watch.
And it looks like the pretty blonde experimented with her barnet, shunning her usual tousled waves for tighter curls.
Beauty-wise, she showcased a flawless complexion (Mols loves MAC Face and Body Foundation, FYI), plus mega-watt lashes, bold brows and a natural rosy pout.
The twosome stopped by the Adelphi Theatre to watch The Bodyguard, which currently stars singer Beverley Knight as the lead role, Rachel Marron.
And it seems Mollie enjoyed her evening, later tweeting: "Just seen THE most incredible musical @TheBodyguardUK!!! @BeverleyKnight was truly spectacular, I'm lost for words, and SO lovely too!"
The songstress and her music producer beau also went for a bite to eat, hitting up popular burger joint Five Guys in Covent Garden.
She Instagrammed a snap of herself clutching a delicious looking burger, adding the caption: "It's a salad really... I promise @FiveGuysUK."
Well, burgers do have lettuce and tomatoes after all...
