Pippa Middleton pregnant, reveals baby bump at Queen’s jubilee party

Appearing at the star-studded “Party at the Palace” concert for the Queen’s Platinum Jubilee, Pippa Middleton’s little secret soon became obvious.

Pippa Middleton is expanding her brood.

The sister of Kate Middleton, the Duchess of Cambridge, was spotted at the star-studded “Party at the Palace” concert in London Saturday with a noticeable baby bump.

Speaking to Page Six, a source said that the couple is “so happy” and Pippa is a “natural mama.”

Pippa, 38, married James Matthews, a hedge fund manager and heir to the lairdship of Glen Affric in 2017. They share two children, Arthur, 3, and Grace, 1.

She is reportedly very close with her older sister, Catherine.

The columnist shot to global fame when she served as a bridesmaid when Catherine married Prince William. Her figure nabbed massive attention when she wore a form-fitting Alexander McQueen gown to the 2011 nuptials.

She even wrote about the ensuing media attention comparing it to Kim Kardashian’s bottom.

“I must say that [my backside] — though it has enjoyed fleeting fame — is not comparable [to Kardashian’s],” Middleton wrote in a column for the UK’s Spectator.

A year after her marriage, she and Matthews purchased Bucklebury Farm, a 70-acre deer and safari park in West Berkshire.

In honour of the Queen’s Platinum Jubilee, the farm has been hosting family events spanning four days in celebration of the Queen’s 70-year reign.

Pippa joined her sister and brother-in-law at the massive concert along with a host of royals including Prince Charles, Prince George, Princess Charlotte, Princess Anne and Prince Edward.

Musical acts include Queen, Diana Ross, Elton John, Duran Duran and Rod Stewart.

The Queen kicked off the festivities with a prerecorded video in which she and Paddington Bear tapped out the beginning handclaps to Queen’s “We Will Rock You” on their teacups.

A spokesperson for Middleton declined to comment.
