Princess Kate attends last official engagement before maternity leave

Kate, 36, is due to deliver her third child next month.

Princess Kate was blooming today as she stepped out for her last royal engagement before going on maternity leave for her third child.

“Today’s public engagements by the Duke and Duchess of Cambridge will be Her Royal Highness’ last before starting her maternity leave," said a Kensington Palace spokeswoman.

Kate, 36, and William, 35, met with athletes at Olympic Park. William jumped in to participate in a wheelchair basketball match and appeared to surprise even himself when he scored a basket.

Kate shared that George and Charlotte love cooking with her and one of their favorite things is getting messy making pizza dough.

Last month, Kate joked that William was “in denial” about their third child and William told a well-wisher that he was already exhausted from George and Charlotte.

What's next for Kate

Kate plans to have her baby again at the Lindo Wing at St. Mary’s Hospital in London, where she gave birth to both George and Charlotte.

The soon-to-be mother of three will take time off for maternity leave.

However, if her pregnancy is delayed and she gives birth in May, Kensington Palace may re-evaluate her schedule.

William and Kate have spoken of the support they receive from family members and their nanny, Maria Theresa Borrallo, in raising two children while juggling royal obligations and charitable work. There is speculation they may hire a second nanny to help with the addition to their growing family.

Kate is expected to return to royal duties after about six months, as she did after her last pregnancy.

Kate's pregnancy style

Kate, who wore a pair of skinny jeans and stylish white coat today, has been busy with multiple engagements over the past few weeks.

She spoke Wednesday about the importance of early intervention for children who may be trying to cope with mental health issues and the challenges of growing up. Kate launched a major new initiative, an early years steering group, that will look at ways of improving how society supports children so they have the resilience to cope with life’s pressures when adults.

She also joined Markle, along with Harry and William, at a question and answer session in February for their Royal Foundation, outlining their charitable aims for the future.
