Pippa Middleton has decided cut her hair short.

Pippa, 34, was spotted sporting a new haircut during her recent bike ride in London. Kate Middleton's sister had a shoulder-length bob, styled sleek and straight with a center part, Hello! reported.

During her outing, Middleton wore a checkered shirt and a pair of black skinny jeans. She completed her look with white trainers and large sunglasses.

According to the publication, Kate's shorter hair might have inspired her younger sister. In July, the Duchess of Cambridge made headlines when she stepped out to visit Wimbledon officials and players with her new haircut.

Pippa and Kate share a close bond as sisters. In fact, the former was the latter's maid of honor during her wedding with Prince William in 2011. And while Kate did not play the same role for Pippa's wedding, she was there by her side to show support. Additionally, when Pippa tied the knot with James Matthews in May, her nephew, Prince George, and niece, Princess Charlotte, were among the entourage during the nuptials, which was dubbed the "wedding of the year."

Aside from the Middleton sisters' participation in each other's weddings, the siblings reportedly wanted to get pregnant around the same time. "It's long been a dream for Kate and Pippa to be pregnant at the same time," a source close to the Middleton family revealed. "To share that would be amazing."

Kate's third pregnancy was confirmed last week. The Duchess of Cambridge is reportedly on bed rest at the moment because she is suffering from hyperemesis gravidarum. The same condition plagued her during her first and second pregnancy as well. Many are hoping to hear Pippa's pregnancy announcement in the near future, especially since she and Matthews are eager to expand their family.

"Being a family man has always been James' main focus, and Pippa comes from a very loving and tight-knit family," one source said. "They can't wait to have a baby. She's already envisioning her children playing with their cousins at Kensington Palace."

The source added that Pippa and Matthews want to have three kids. The former has had her fair share of experience when it comes to caring for children as she is a doting aunt to Prince George and Princess Charlotte.
