Kelly Osbourne drew concern from worried fans on Saturday evening as she stepped out wearing a leg brace in Los Angeles. Later on Instagram, the TV presenter took a shot of her "Robocop boot" and revealed she had suffered a stress fracture.
"#StressFractures are the worst! At least I get a cool #RoboCopBoot", Kelly captioned the snap.
The 29-year-old star was attending the 2014 Trevor Project NextGen Prom with pal Amanda Golombek and had styled her recently shorn off hair in to a stylish quiff.
Wearing a gorgeous black lace dress, Kelly showed off her svelte figure - which she maintains through healthy eating and regular workouts with a personal trainer. After Kelly split from her fiancé Matthew Mosshart she was said to have gained weight. But she disputed this - and shared her annoyance over the media's obsession with her figure.
