British Prime Minister Boris Johnson and his partner Carrie Symonds are engaged and expecting a baby in early summer, according to multiple reports Saturday.

Johnson, 55, and Symonds, 31, became the first unmarried couple to occupy Downing Street when they moved in last July. Symonds is also the youngest partner of a prime minister in 174 years, according to BBC News.

In a post on her private Instagram account, Symonds gushed: “Many of you already know but for my friends that still don’t, we got engaged at the end of last year… and we’ve got a baby hatching early summer. Feel incredibly blessed,” the BBC report said.

Johnson is hoping third time’s a charm. He divorced his first wife and is now estranged from second wife Marina Wheeler. The couple separated in 2018 after tying the knot in 1993. Johnson has four children from that marriage.

A family court judge on Tuesday approved an undisclosed financial settlement and gave Wheeler permission to apply for a divorce decree, according to The Guardian.

British tabloids took to calling Symonds the “First Squeeze” or “First Girlfriend” as they scrutinized everything from the couple’s relationship to her posh fashion choices, The Post reported in July.

Symonds worked as part of the campaign team that helped to get Johnson reelected as mayor of London in 2012.
