The Shake It Up star stepped out at YouTube music festival DigiFest at the Hollywood Palladium in Los Angeles, where she later performed and answered audience questions.
The stunning starlet ditched the frocks for a more laid-back look, sporting loose purple trousers which featured navy stripes running up each side.
She paired her comfy joggers with an intricate silver top and chunky black boots complete with white soles.
Like Bella we're all about the clumpy boot this season, and if you fancy getting in on the trend too check out these Chelsea boots, £40 from River Island.
To complete her look the actress added a few silver bangles while showcasing fluttery lashes and a nude pout.
And in true Bella style she pulled out all the stops with her barnet, flaunting a beautiful half-up, half-down 'do with boho braids and loose waves aplenty.
