The Shake It Up star attended the premiere for the new TMNT film in Los Angeles yesterday (3 August), and decided to pay homage to the show with a super-cute tee...
The starlet even did a bit of DIY customisation for the event, giving her graphic print top a sultry edge by chopping the neckline into an off-the-shoulder design. The sleeves of her T-shirt were also dotted with square gold studs for a rock chick feel. We like!
Upping the glam factor, the 'Call It Whatever' singer rocked a little leather miniskirt with exposed silver zips while accessorising with heaps of gold bracelets.
She also made a statement with her footwear, sporting a pair of towering caged peep-toe heels while toting all her red carpet essentials in a perspex black and neon yellow clutch.
Beauty-wise, Bella lacquered her talons a sizzling white shade and decorated her peepers with green shimmery shadow (very turtle-esque!), before topping off her look with a rosy pink pout.
Who knew an old cartoon tee could look so good?!
