Did Meghan Markle share this skincare tip with Serena Williams?

Serena Williams gave a hint that she and Meghan Markle are in regular contact as she appeared to share a skincare tip from the duchess.

Williams appears on the cover of Vogue this month, and alongside her interview, she filmed a video with the magazine showing what was in her handbag.

Williams, 39, told viewers she’s “really obsessed nowadays with a lot of beauty stuff” as she shared her favourite eye mask and a chin mask.

She said: “The chin mask I can do when I drive.

“It’s a chin and jaw mask, and I’m laughing but I am very serious.

“It keeps your jaw and chin firm. A really good friend of mine told me that but I never said her name, never seen her, never heard her, don’t know her.”

The mask is by facialist Sarah Chapman, who worked with Meghan before her wedding to Prince Harry.

Williams has previously made a ‘never heard her’ reference to Meghan, and is rarely drawn on their friendship in public.

In an interview with Naomi Campbell, she was asked: “Are you happy that your girlfriend's moved to America? Meghan Markle.”

Williams replied: “Don't know what you're talking about, don't know nothing about that.”

Avoiding a push from Campbell to share some news, she added: “Never seen her, never heard of her, don't know her.”

The tennis superstar and the former actor have been friends for several years, having met in 2010 at a Super Bowl party. Williams attended Harry and Meghan’s wedding in 2018, and Meghan has supported the Grand Slam champion from the stands of several matches.

Williams has spoken about her a few times in the past but has kept quieter about her royal friend of late.

In a profile about Meghan before she married Harry, Williams said: “I told her, ‘You’ve got to be who you are, Meghan. You can’t hide’.”

When Meghan wore a blazer from Williams’ clothing line, the tennis player and mother of one posted a smiling photo of the duchess on Instagram about the support, writing: “The face you make when you and Duchess of Sussex Meghan have matching @serena blazers.”

Facialist Chapman, who runs Skinesis, posted about Meghan on Instagram shortly after the Duke and Duchess of Sussex stepped back from their senior royal duties.

She said: “With Meghan, what began as a client relationship quickly turned into a dear friendship and she welcomed me into their lives. I feel very grateful to be a small part of their journey observing the passion for everything they do and compassion for the causes and people they meet, but also to witness the moments other people don’t see.”
