Kate Middleton's Baby Bump Sighted On London Shopping Trip (VIDEO)

Kate Middleton on her way to a pharmacy in London on Wednesday. Middleton's outfit frustrated paparazzi eager to photograph her growing baby bump. 

"Debut" might be a strong word, but Kate Middleton did finally reveal a hint of baby bump to the world this weekend. The British paparazzi caught the Duchess of Cambridge out and about last week, shopping at Boots in West London.

Kate was wearing her typical off-duty gear -- skinny pants, suede boots, ponytail -- with one exception: a swingy tartan cape-like jacket from Zara, which cascaded gracefully over what appears to be a visibly pregnant tummy. British tabloids touted the photo as the "first look" at the bump, which means the Royal Bump Watch has officially begun, or something.

While her formal appearances have been few and far between lately, the duchess has reportedly been shopping up a storm. Tabloids have spotted her looking for jeggings at Gap, maternity threads at London's JoJo Maman Bébé and trendy yoga gear at Sweaty Betty, supposedly quenching her thirst at a Starbucks. ($10 says she asked for no whip.)

The most famous baby bump in the world - with apologies to Kim Kardashian - surfaced on a rare sojourn in public last week.

Let's hope she keeps up the shopping frenzy -- how else will the Royal Bump Watch continue?
