Lynn Wyatt believes that Nicole Kidman is "beautiful inside and out."

The 77-year-old socialite was a dear friend of Grace Kelly Princess of Monaco before the Hollywood legend passed away in 1982.

Nicole depicts the royal in upcoming biopic Grace of Monaco and Lynn couldn't be happier about the casting.

"First of all, I know Nicole Kidman. There is nobody more gorgeous," Lynn Wyatt told People magazine Monday at the 30th Anniversary Princess Grace Awards Gala hosted by the Princess Grace Foundation-USA in New York City.

"She's beautiful inside and out, and she's very sweet. She's very nice and she's caring. I think she would be perfect."

Although Lynn thinks Nicole is fantastic, she misses her friend Grace.

The socialite believes that Grace was a phenomenal human being.

"But there was nobody like Princess Grace. I think it's flattering to have somebody play you like that and of all people, Nicole would be the right one but I remember I was at the Monte Carlo Beach Club, and she had all her hair up under this big hat, and I said, 'Excuse me, Grace, I'm staring at you.' " she recalled.

"You know, when you're good friends with someone you know them more inside than out, but her cheekbones, and just the way her eyes [looked], everything under that big hat, she was just so beautiful. I just said 'Grace, forgive me, but I'm staring at you.' And she just said, 'Oh, Lynn.' "
