The Duchess of Sussex flew on a commercial plane to New York today to watch her friend Serena Williams play in the final of the US Open.
The mother of one is believed to be flying alone across the Atlantic – leaving Harry and their four-month-old son Archie in Windsor – although a security team is said to be with her.
Meghan will cheer on Serena as she plays against Bianca Andreescu in Queens tomorrow as the former world number one again tries to equal the all-time grand slam record.
The Duchess, who also watched Williams at Wimbledon in July, flew out following the row over the royal couple taking four trips by private jet in 11 days last month.
Meghan stayed up to watch the semi-final, which ended at 1.30am today UK time, and is thought to have boarded a flight in London at about 8.30am this morning.
Meghan is expected to return to Britain on Sunday. A source told The Times: ‘It is a last-minute trip. Excited to support her friend, and then come back.’
This is Meghan’s first trip to New York since her baby shower in February when she partied for five nights at a £57,000-a-night penthouse with her celebrity friends.
The party, which caused disquiet in Britain due to its eye-watering estimated total bill of £330,000, was hosted by Williams and her long-standing friend Jessica Mulroney.
Meghan flew to and from the US on that occasion on a private jet with her close friend Amal Clooney, who paid for the 13-hour round trip which cost £13,277 an hour
Meghan first met Williams at a Super Bowl party in 2010, and their friendship is thought to have quickly evolved through frequent phone calls and texts.
