THE royals aren't exactly cash-strapped, but Serena Williams has served up a treat ahead of Baby Sussex's arrival by sending the parents-to-be a nappy delivery.
Speaking as Pampers' latest spokesmodel, the tennis ace revealed she had shipped the products to pal Meghan Markle, 37, who's expecting her first child with Prince Harry any day now.
about the collaboration, Serena, 37, teased: "I may have already sent Pampers across the pond."
Serena, who has a 19-month-old daughter named Olympia, met the Duchess of Sussex at a charity flag American football game in February 2014 - and immediately hit it off.
They've remained close since Meghan moved to Britain, with Serena bagging invites to the May Royal Wedding and Meghan's £330,000 New York baby shower - and the duchess was seen cheering her on at Wimbledon with Kate Middleton, 36, last summer.
Gushing about her friend, Serena this week: "She'll be the best mum, for sure."
Writing on her now-deleted blog The Tig, Meghan said of Serena: "We hit it off immediately.
"Taking pictures, laughing through the flag football game we were both playing in, and chatting not about tennis or acting, but about all the good old fashioned girly stuff.
"So began our friendship."
