The 33-year-old, known for her natural curves, describes herself as "a natural" and believes in saying the right thing.
"I truly believe that beauty comes from within. If you're happy then not only will you look better, you'll be a good partner and a good friend too," You magazine quoted Brook as saying.
"I'm careful with the message I give out. I am natural. I don't have hair extensions or anything like that," she added.
Brook feels girls, who go under the knife, are not happy with themselves.
"I'm not the person who says, '...I have Botox every two months and look at me, aren't I great?' I think those girls are actually really sad and are not very happy in themselves," Brook said.
