Kate Middleton‘s younger brother, 32, privately proposed to Thevenet, a French financial analyst based in London, according to the Daily Mail, which added that he is set to formally announce the good news next week. “They’ve been keeping the engagement secret, but news has started to leak out among their friends,” one of their friends told the outlet, adding that Thevenet “has been wearing a beautiful sapphire sparkler” on her finger. Although the couple has kept their romance mostly under wraps, James brought Thevenet along to a family vacation in St. Barts with James’ sister Pippa, 36, and her husband James Matthews in January. The couple was previously seen together in December 2018, when they went to the Henry van Straubenzee Memorial Fund’s Christmas Carol Service at St. Luke’s Church. Over the summer, James also shared a candid photo of his golden retriever Mabel excitedly jumping into the pool as Thevenet sported a red bikini. “I had the chance to grew up in six different countries: Germany, Indonesia, Chile, France, Belgium and England,” Thevenet said on her LinkedIn profile, in which she describes herself as having a “multinational background.” Back in 2018, James’ mother Carole Middleton, opened up about her hopes for her son’s love life with U.K. newspaper The Telegraph, saying she hoped to have a “lovely daughter-in-law” someday. “I’m definitely hands-on. I don’t find it complicated,” Carole said of her approach to motherhood. “My biggest fear [as her children grew up] was that I’d lose my family, but we’ve stayed close. There are times when they say, ‘Can you do this, or that?’ And I can’t quite. But they like the fact that I work. I have two lovely sons-in-law, and I hope I’ll have a lovely daughter-in-law.” James previously dated actress Donna Air, who is seven years his senior and has a daughter named Freya.
