Expectant mother Pippa Middleton stepped out to Roland Garros in Paris with husband James Matthews to enjoy a day of tennis.
Pippa, who is believed to be four months pregnant, concealed her growing baby bump in red Ralph Lauren wrap dress, dotted with celestial patterns in white. A hint of her tiny bump was just visible beneath the flowing dress.
The younger sister of Duchess Catherine was spotted walking around the French open venue hand-in-hand with James. The couple carried matching trilby hats, Pippa's with a red ribbon detail to match her dress, James' with blue.
The pair took their seats in the crowd among other tennis fans. Pippa rested her hand on her husband's thigh as the pair chatted to each other and watched the first round matches.
Just last week Pippa, 33, and James, 42, attended the wedding of Prince Harry and Meghan Markle, where royal watchers were keen to catch a glimpse of her baby bump under her floral dress by British label Ford.
The couple haven't officially confirmed their pregnancy yet. They married in a lavish ceremony in May, 2017.
It appears 2018 will be a big year for babies for the Middleton and Matthews family, with Duchess Catherine welcoming her third child, Prince Louis, one month ago, Pippa expected to give birth in October, and James Matthews younger brother Spencer Matthews and his fiancée Vogue Williams, 32, preparing to welcome their first child together in September.
The Sun confirmed in April that Pippa was expecting her first child with her husband James.
The publication reported the couple told friends and family after a successful 12-week scan.
A source told The Sun that Pippa's sister, Duchess Catherine "could not have been more delighted" with the exciting news.
"When Pippa found out she was pregnant, she was obviously thrilled and utterly overjoyed," a friend told the publication.
