In the new interview, Serena gushed over her relationship with Meghan, calling her "amazing" and the "strongest person she knows".
"She flew all the way with a newborn to see me play in New York and flew all the way back that night, and I probably couldn't have done that. It just kind of goes to show you what an amazing person that she is, and that's just one of the many things that she does for me." Serena said, also adding that Meghan is "the strongest - literally the strongest - person I know, and the nicest, sweetest."
Despite living on different continents now, Serena also details how the pair stay so close.
"I call her, text her anytime, crying, upset - she's always there. Doesn't matter what she's going through, she just sets time away, and she's just so amazing."
We love their friendship!
