Kate Middleton stepped out for a shopping trip in London on Monday, covering her baby bump in a peacoat and wearing a scarf around her neck. The pregnant princess, who turned 33 last week, was accompanied by two security guards during her trip to the John Lewis department store in Chelsea, where she was spotted carrying several shopping bags. Kate hasn't made an appearance since the royals' Christmas outing, but she's expected to attend a series of events later this week. On Thursday, Kate will visit Barlby Primary School in London for workshops run by The Art Room, an organization that provides art therapy to children, and on Friday, she'll head to The Fostering Network to show her support for foster caregivers.
