"I have no words only inordinate amounts of LOVE ❤️ #RANIROSEROCKS," Hudson's mom, Goldie Hawn wrote.
"Elvis loved watching this. I think we need to start a mommy band Kate!" Amanda Kloots added, while Vanessa Bryant replied, "😍😍😍😍she's so cute!"
"Now my know my ABCS too! Genius @katehudson," Cara Delevingne teased.
"She wants to work out with me," said Hudson, who is also mom to sons Bingham "Bing," 9, and Ryder, 17. "She gets on there, she's doing her butt exercises. She kind of does her own version of them. Turns into a little bit more of a dance move. I'm learning so quickly that this whole 'everything that is mom's is yours' when you're a girl is real."

Hudson added that she plans to pass down some of her favorite fashion pieces to her daughter, explaining that she never got to raid Hawn's closet for her stylish red carpet looks since "Mom is really good at purging and not keeping anything."
"So she kept none of her old clothes, and when I got older, I was like, 'Where are those Alaïa pumps, Mom? Where did you put all of those amazing dresses you wore?' And Mom's like, 'I don't know,' " said Hudson, adding of herself doing the "opposite": "I have everything. I was looking through some of the archives, and I said, when Rani is 16 and opens up this box, I'm going to live through her."
