Duchess Kate can't hide her baby bump any longer!
The 36-year-old royal delivered a speech at Roe Green Junior School on mental health with her baby bump on full display in a powder blue Seraphine frock. The London-based clothing brand has been one of Kate's favorite labels throughout all her pregnancies.
For the rest of her look, she donned a recycled Sportmax coat she first wore while pregnant with Princess Charlotte in 2015, a Beulah scarf and navy blue suede heels.
The Duchess of Cambridge was greeted with a huge crowd filled with young students. Inside the school, she met with teachers and pupils while also observing a class before her big speech.
"The role of teachers here is absolutely vital," she said. "You see our children as they grow, learn and play, as they build their social skills that will make the difference to their futures."
The mother of Charlotte and Prince George was also on hand to launch the pilot of Mentally Healthy Schools, a website aimed at giving teachers resources to help support the mental health of their students.
Mental health has been an issue near and dear to Kate's heart due to the charity she co-founded with Prince Harry and Prince William -- Heads Together. The organization seeks to help people -- from teenagers to military veterans -- become more comfortable with their mental well-being.
Kate's baby No. 3 is due in April, and she shows no signs of slowing down! It's shaping to be a major year for the royal family, with the birth of her baby, Harry and Meghan Markle's wedding in May and Princess Eugenie's wedding in the fall.
