The doting mum-of-two attended a ceremony at the museum she is a patron of, where the new giant blue whale skeleton has been unveiled.
The 83-foot skeleton has been hung from the ceiling in the revamped Hintze Hall, replacing the beloved Dippy the dinosaur.
Kate joined Sir David Attenborough to be among the first people to see the new addition to the museum, where she also showcased her brand new short hair style with loose curls.
Speaking at the event, Kate revealed both Charlotte and George love visiting the world-famous museum.

‘Like many of you here tonight, I remember visiting the Natural History Museum as a child, and being inspired with a love of nature’, she said.
‘And now, as a parent myself, I am experiencing the joy all over again with my own children, who adore coming here, and it is not just to see the T-Rex mind you. Who could fail to be inspired standing here in this wonderful hall.
‘It is so fitting to see the ocean now taking centre stage, with many other marine specimens as star attractions in this splendid Hintze Hall.’
It’s not the first time we’ve had a glimpse into George’s excitement for nature and wildlife and how much he loves the Natural History Museum.
Back in 2014, the venue was the setting chosen by Kate and William for their son’s official birthday pictures when he turned one.

Kate was also pictured by visitors while showing the giant dinosaur, who’s now in a UK tour to be on display in several museums, to Prince George a couple of years ago.
