"She'll be the best mom," the tennis champ says of Meghan Markle

New mom Serena Williams is making sure her friend Meghan Markle is ready for motherhood!

The tennis champion, who stars in a new commercial for Pampers’ Cruisers 360 FIT diapers alongside her 19-month-old daughter Alexis Olympia, is passing on the perks from her new partnership to the royal mom-to-be, who is set to welcome her first child with Prince Harry this month.

“I may have already sent Pampers across the pond,” Williams told Reuters.

The supply of diapers will definitely be useful, but Williams doesn’t think the Duchess of Sussex will need much help as a new parent.

“She’ll be the best mom, for sure,” the athlete recently told E! News.

While speaking to E! News, Williams may have accidentally hinted that Meghan and Harry is having a girl. When asked about advice she had for fellow parents, the tennis star said, “Accept mistakes and don’t expect to be perfect. We put so much pressure on ourselves.”

She then added, “My friend is pregnant, and she was like, ‘My kid’s gonna do this,’ [and] I just looked at her like, ‘No, she’s not. No, you’re not. She was like, ‘I need to talk to you about tips,’ because, yes, I had all of those high expectations.” Could Meghan be that pregnant pal – and did she slip that the baby is a she? (Of course, Meghan previously said that they didn’t know if they were having a boy or girl, adding that they wanted it to be a surprise.)

Williams previously told PEOPLE that Meghan hasn’t changed one bit — despite juggling her busy new role as a royal while being pregnant for the first time.

“I’m like, ‘How are you?’ and she’s like, ‘No, how are you?’ and I’m like, ‘You’re so sweet, but I’m really asking – how are YOU?’ ” she said. “I’m like, ‘Meghan, stop being so nice…you’re the pregnant one, aren’t you supposed to have hormones, why are you so sweet?’ But that’s always been her.”

The star athlete also shared that while she is giving the Duchess of Sussex plenty of advice from one new mom to a soon-to-be parent, Meghan “still gives me more advice.”

The two women first met at the Super Bowl in 2010 and immediately hit it off. They also appeared together at the 2014 Super Bowl, competing in DIRECTV’s Celebrity Beach Bowl.

Williams attended Meghan and Harry’s royal wedding last May and played a big role in planning the mom-to-be’s baby shower in New York City in February. The tennis star even snapped a selfie inside The Mark Hotel, where the bash was held. The hotel is known for its black and white striped floors, which are prominent in Williams’ snaps, along with a robe featuring the hot spot’s logo.

Guests at the shower – which was also attended by Amal Clooney, Serena Williams, Gayle King, Jessica Mulroney, Misha Nonoo and Abigail Spencer – were treated to a flower-arranging class and plenty of delicious food.

“It was exactly what she needed, and it was a reunion for all of us, too, who hadn’t seen each other since the wedding,” Meghan’s longtime friend and wedding makeup artist Daniel Martin told PEOPLE.

“Snow was falling outside, and it was so cozy — we all sat on couches or on the floor and told stories and caught up,” he adds. “It was like going to a family reunion.”

Adds another attendee: “It was all baby talk. She was getting tons of advice.”
