Did Jennifer break Demi's foot?

Demi Lovato is finally coming clean about why she was forced to wear a (studded!) cast on her broken foot from February through April. Demi claims it was really all Jennifer Lawrence's fault! "I was watching Silver Linings Playbook, and 10 minutes into the movie, I got up to get a popsicle," Demi says. "My roommate had pledged the floors that's what she thought you're supposed to clean hardwood floors with and I slipped and fell.But I blame it on Jennifer Lawrence. It's all her fault since I was watching Silver Linings Playbook."
