Congratulations may be in order for Pippa Middleton and her new husband, James Matthews! According to Woman’s Day, Kate Middleton’s 33-year-old sister is pregnant with her first child. “Pippa always said she wanted to start a family as soon as she got married, and now her wish has come true,” a source revealed on Monday, Aug. 28.

“It’s early days yet — and they have decided they don’t want to know the sex of their baby until after it’s born — but Pippa is convinced she is having a little girl,” the insider continued. Last week, Pippa, believed to be two months along, was spotted out in London in a flowing top to hide her bump. She worked out endlessly to get in shape for her wedding, and friends say she won’t be giving up her workout regimen during her pregnancy.

“She has seen other fit and healthy moms-to-be with a small, neat baby bump — and she’s hoping to stay as active as possible right up until the baby is born,” the source explained. While Pippa is having some morning sickness, sources say the London-based socialite isn’t suffering as much as her sister Kate, 35, who was hospitalized during both her pregnancies. “She has missed a few gym sessions and was due to go cycling with friends, which she had to cancel. But it’s not bad like Kate’s was,” the insider said.

Already a doting aunt to Prince George, 4, and Princess Charlotte, 2, there’s no doubt Pippa will be a wonderful mother! In the past, Pippa has opened up about her mother Carole Middleton’s tough love approach to raising her children. “We were taught to eat properly and to eat together as a family three times a day,” she told the Daily Mail last year, recalling her childhood in the village of Berkshire.

“As children, we didn’t have anything different, we always ate what our parents ate. My mother and father took the view, and I agree, that you don’t need to make different food for children,” Pippa continued. “We had to eat everything on our plate and not be fussy about food. There were times when I would be sitting at the table after lunch or dinner, having not eaten something because I decided I didn’t like it and actually remaining there until I had eaten it.”

In May, the world’s most famous bridesmaid became the bride after tying the knot with James in an extravagant ceremony at St Marks’s Church in Englefield. After their lavish nuptials, the pair enjoyed a month-long honeymoon in destinations all around the world including Australia, New Zealand, Scotland, and French Polynesia. They’ve since returned to their sprawling West London mansion, which would have plenty of appropriate rooms for a nursery!
