Popsugar Celebrity Pippa Middleton Pippa Middleton at 2019 British Heart Foundation Ball Pippa Middleton Has That Post-Baby Glow During Her First Official Appearance as a Mum 27 February 2019 by Monica Sisavat Solís Image Source: Getty / Stuart C. Wilson She's back! Just four months after welcoming her first child with husband James Matthews, Pippa Middleton stepped out for her first official appearance at the Beating Hearts Ball in London on Wednesday. The ball is in support of The British Heart Foundation, and the 35-year-old mum is the foundation's honourary gala chair and ambassador. Dressed in a red and black Temperley dress, Pippa looked radiant as she flashed a big smile for the cameras. Wow, that post-baby glow is real! Even though James didn't hit the red carpet with Pippa, according to People, he was in attendance. Pippa and James tied the knot back in May 2017 and became parents to a baby boy named Arthur Michael William this past October. Even though this marks Pippa's first red carpet appearance since giving birth, she and James went Christmas Caroling with Prince Harry and Meghan Markle over the holidays, and the couple rang in the new year with a fun trip to St. Barts. We still have yet to get a glimpse of baby Arthur, but something tells us he's adorable! Image Source: Getty / David M. Benett 1 / 11 Image Source: Getty / Stuart C.
