Rebel Wilson has lost a staggering 20 kilograms as part of her 'year of health'.

And the 40-year-old proved she isn't shy when it comes to flaunting her new physique as she attended a Halloween party in Los Angeles on Saturday. 

Dressing up as a 'coronavirus  killer', the slimmed-down star wore a skimpy black leotard which featured a midriff cut-out and silver material across the bust.
