Tennis ace Serena Williams joked she had never heard of Meghan Markle in a video call with Naomi Campbell.

The British supermodel chatted with Serena and her sister Venus in the latest episode of her YouTube series, No Filter With Naomi. 

Campbell asked Williams: "Are you happy that your girlfriend’s moved to America?" It comes after Markle has relocated to Los Angeles with Prince Harry and their son Archie. 

The 23-time grand slam winner replied: "I don’t know what you’re talking about, I don’t know nothing about that.

"Never seen her, never heard of her, don’t know her."

Williams and Markle formed a friendship after they met in 2010, with the tennis star then attending the royal wedding in 2018, and Markle going to the US Open a year later.

But it is not the first time Williams has avoided questions to do with the Duchess of Sussex.

At the start of the year during the Australian Open a reporter asked her what she thought about Harry and Meghan's decision to step away from the royal family. 

But Williams, once again volleyed away the question and said she had 'no comments on anything with that'.
