Kate Middleton is back to fulfilling her royal duties after weeks of bedrest.

On Monday, Middleton made her second public appearance since the announcement of her third pregnancy at the Paddington Station in London. The Duchess of Cambridge graced the charity event with Prince William and Prince Harry, along with the cast members of "Paddington 2," Daily Mail reported.

Middleton also debuted her new hairstyle at the event. The mom-of-two sported bouncy curls and wore an Orla Kiely raised flower fitted dress. The Duchess of Cambridge paired it with black shoes and purse.

In the photos shared by Daily Mail, Middleton had some fun goofing around and dancing with Paddington Bear. She and the bear danced to the tune of calypso band D-Lime, who played the soundtrack of the first and second "Paddington" films. Middleton showcased her dancing skills as Paddington Bear twirled her around, while the Duke of Cambridge laughed and watched them from the side.

Middleton made her first public appearance after Kensington Palace announced her third pregnancy at a reception for World Mental Health Day. The event was a celebration of the contributions of those working in the mental health sector across the UK. Middleton, Prince William and Prince Harry are all active advocates of mental health.

Since it was Middleton's first public sighting, many were looking forward to seeing her growing baby bump. However, her tummy was not as big as what most expected, so the Duchess was bump-shamed for her tiny bump.

In the photo shared by KensingtonRoyal on Instagram, a number of critics questioned Middleton's pregnancy. "I can't believe she's prego, she looks too thin," one user commented. "Really, Is she pregnant?" another user wrote. Meanwhile, others attacked Middleton's looks and described her as "malnourished," "anorexic" and "emaciated."

But while there were some criticism, majority showed their support for Middleton. "Yeayyyy our duchess is BACK," one follower commented. "Love them and everything they do to raise awareness. Glad The Duchess is feeling better," another one wrote.
