Pregnant Meghan Markle Shows Off Growing Baby Bump at Natural History Museum Gala—See the Pics

Meghan Markle and her growing baby bump stepped out for a night on the town with Prince Harry on Tuesday.

The Duke and Duchess of Sussex made an appearance at the Natural History Museum in London in support of the Queen's Commonwealth Trust, a royal organization that "champions, funds and connects young leaders who are working hard to change the world," according to the group's website. The gala was held in conjunction with the Queen's Commonwealth Canopy, which provides services towards conservation efforts aimed at saving and preserving forests.

Markle's pregnant belly was on full display at the event, which included a special presentation of The Wider Earth. The duchess, who is nearing her due date, showed off her growing bump in a body-hugging, white turtleneck dress by Calvin Klein, Us Weekly reported, paired with olive green suede heels by Ralph Lauren. Markle topped her radiant look off with a white, knee-length coat made by designer Amanda Wakeley.

Her husband was similarly dashing in a navy blue suit paired with a grey tie.

Markle and Harry are expecting the arrival of their first child together rather soon. Although the 37-year-old's due date hasn't been revealed, Markle recently noted she was getting closer and closer to delivery time.

While speaking with members of the public at a January outing in Birkenhead, Merseyside, Markle said she only had about three months to go become the royal baby's arrival. "We asked her how her pregnancy was going and she said she was six months and she tapped her tummy," Carla Gandy, a Wallasey resident, told People magazine at the time.

When Kensington Palace first announced the couple was expecting a baby, it said the child was due sometime in the spring. With Markle entering her seventh-month in February, it's likely the new royal will make his or her appearance in April.

The couple has yet to reveal whether they are expecting a boy or a girl.
