Sporting two diamond studs on either side of her face, she paired her cheek piercings (or 'dimple piercings') with enormous sunglasses and a toque, and, on another occasion, with a curly blond wig and fake nails.
The 26-year-old starlet has been posting a flurry of random and nonsensical tweets lately, including pictures of her socks (appropriately captioned 'SoCks'), her thoughts on rocking the 'Incest Face' (whatever that means) and how she's invented catch-phrases we've never heard of ('Ily & lololol.')
Aside from her dramatic makeover and her strange behaviour on social media, Bynes has also had her share of legal trouble lately -- she's been charged with several DUIs and there's been speculation of drug use.
While her behaviour may be odd, Bynes isn't the only celeb sporting studs; in fact, Hollywood seems to be big on poking holes in creative places.
