Kate Middleton's latest real mom moment came late last month, when she and a friend took Prince George out for a casual stroll around London. The Duchess of Cambridge has been photographed walking with George near their Kensington Palace home before, though this is the first time she's done so with a pal. It's been an exciting few months for George, who turned 1 on July 22 and also completed his first overseas royal tour in the Spring. The family of three traveled to New Zealand and Australia, and George made more than one public appearance, making for plenty of adorable photos of the little heir. His parents gave us another glimpse at George in their latest official portraits, which were released to celebrate George's first birthday.

He might not be an only child much longer, since rumors are starting to swirl that Kate and Prince William are looking to expand their family further. Some sources are even saying that Kate is already pregnant, though her turquoise tank doesn't reveal much more than her bra straps.
