"Gettin cray on this juice #Luca'sstash," Duff captioned the photo. In the snapshot, Duff holds a tiny box of pear juice to her face and pretends to sip from the straw while making a silly face. The juice joke is obviously referencing some sort of alcoholic beverage, which Duff clearly isn't drinking.
Duf has been getting on with her life post-split and has taken to Twitter to slam reports that her and Comrie's separation is anything less than mutual and friendly.
"Don't believe the s--t you read! & don't buy trash magazines!" she wrote yesterday. "They are so gross and so negative. They literally make my skin crawl."
Duff and Comrie announced they were parting ways last Friday. "Hilary Duff and husband Mike Comrie have mutually decided to an amicable separation," Duff's rep told E! News in a statement. "They remain best friends and will continue to be in each other's lives. They are dedicated to loving and parenting their amazing son, and ask for privacy at this time."
Since then, Duff was spotted hitting the gym without her wedding ring.
