Meghan previously gushed about her longtime pal in an interview with Vogue, praising the athlete and calling her an "amazing mother." Serena later returned the favor while speaking with People, saying Meghan hasn't changed one bit since becoming a royal. "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 athlete also threw Meghan an epic baby shower in NYC back in February that reportedly cost a whopping $200,000!
