She might have almost two years of motherhood under her belt, but tennis superstar Serena Williams won't be offering her friend, the Duchess of Sussex Meghan Markle, any parenting advice - at least not yet.
During a chat with BBC Breakfast ahead of her appearance at Wimbledon, Williams, mum to toddler Olympia, shared that she never passes on "words of wisdom".
"I feel like for everyone — when they have a kid, especially when you just have a baby — it's so difficult to just be," she said. "It's just like, 'Get through the first three and then four months, and then we can talk.'"
The Duke and Duchess of Sussex welcomed baby Archie in early May. But while Meghan might only be two months into parenthood, it's likely she'll welcome any advice from Williams, who co-hosted Markle's New York baby shower, with open arms.
In an interview with Vogue, the Duchess of Sussex said of a pregnant Williams: "She will be an amazing mum. The very best, because she is so attuned to balancing strength and sensitivity. Plus, given that she is pretty epic at karaoke, I think she'll put her signature Serena spin on singing lullabies for the baby. I can't wait for that!"
Williams won't necessarily agree with her Royal BFF's assessment, however, describing herself as a "mess" when it comes to parenting.
"I just put on some concealer and I'm here. I'm pretending that everything's fine," she told BBC Breakfast.
As Williams chases her 24th Grand Slam title, she admitted that becoming a mum has changed her perspective on many things. "It also has changed me in a terms of ... I want to leave a legacy," she said. " I want to be this positive person for my daughter. Everything I do, I want to do it for my daughter, and I've never, obviously, had that motivation before."
The 37-year-old, who is married to Reddit co-founder Alexis Ohanian, also spoke of the challenges of raising children in a world of social media. "For me it's really important to believe in yourself ... and it's hard. I can't imagine growing up nowadays in this time but I have to imagine because I have a daughter who's going to grow up in this time so I kind of need to put myself in that situation and what do I want out of that?" she said. "So that's how it kind of starts and then for me, I do have a voice that I can use and how do I use that in a positive way?"
And she's taken notes from her own upbringing, too. "I think parents nowadays are like 'Oh we want this, we want our kids to do this ...' but we didn't turn out that bad," she said. "So, you know, I'm going to incorporate a lot of the stuff our parents did with me. I had a really good environment growing up and loved having sisters around."
So are siblings on the cards for Olympia, then? Not just yet.
"I can't provide that for Olympia just right now," she said. "Who knows!"
