Catherine, Princess of Wales (aka Kate Middleton) greets onlookers and staff outside of the Royal Surrey County Hospital's Maternity Unit on Wednesday (October 5) in Guildford, England.

According to royal reporter Rebecca English, the 40-year-old Princess got to hear all about the holistic support and mental health support the hospital provides for expectant moms.

She also met with staff at the Special Care Baby Unit to hear about their neonatal care for premature babies.

If you missed it, this week, a ton of bombshells were revealed in a new royal book (including what "irritated" King Charles about the media attention given to the new Princess of Wales.)

FYI: Princess Catherine is wearing a Karen Millen dress (and it's currently on sale!) Fans took to Twitter as photos of her appearance became available and this seems to be a fan fave look!
