BFF forever! Serena Williams reveals she sent princess markle pampers across the pond

Serena Williams has been there for best friend  throughout her pregnancy by throwing her a lavish New York City baby shower — and now the tennis player revealed she stocked the duchess up on diapers.

The 37-year-old tennis player and mom to Olympia, one, has teamed up with Pampers diapers as a spokesperson for the brand.

When speaking with about the collaboration, Serena admitted she 'already sent Pampers across the pond'.

The recipient of those diapers would be none other than the Duchess of Sussex, 37, who is expected to give birth to she and Prince Harry's first child in a matter of weeks.

Serena has helped Meghan navigate her pregnancy as she was one of the main people responsible for planning the lavish baby shower that happened in New York City back in February.

The festivities — hosted with the help of Amal Clooney —  took place in The Mark Hotel's two-story Grand Penthouse Suite in the Upper West Side. Serena, according to , selected the location after visiting several other venues.

The suite costs $75,000 per night making it one of the most expensive per-night hotel rooms in the U.S. — and Serena reportedly also picked up the tab.

As well as commenting on her ability to stock Meghan's changing table, Serena also revealed how she thought her friend would be in her new role as a mother.

'She'll be the best mom, for sure,' Serena told .

These statements come as Serena released a commercial about motherhood for Pampers starring her daughter, Olympia.

The campaign, entitled the Pampers Cruisers 360 Fit Wild Child program, encourages children to be their wildest selves while wearing their diapers.
