Yesterday we spotted a barefaced Hilary Duff leaving her pilates class in Los Angeles with a smile and showing off her growing pregnant belly.

The actress hasn't let pregnancy slow her down. She's been busy doing a book signing tour promoting her new novel, "Elixir," a sequel to her first novel "Devoted."

She stars in the upcoming film "She Wants Me" about a neurotic writer who gets into a tricky situation when an A-list actress shows interest in the role intended for his girlfriend.
