The `What`s My Name` singer is on very familiar terms with female rapper Nicki, who said they became close after she sent Rihanna verses she recorded to use on her album.
Nicki told RWD Magazine: "She didn`t wind up using the things that I sent for that album at that time, but we wound up having a mutual respect for each other.
"So I knew eventually something would happen. And so now when she sees me she fondles me and stuff like that.
"She fondled me at the MTV Video Music Awards and the American Music Awards. I love her. Right now she`s the girl that everybody loves. I`m so proud to have worked with her.
"Let`s just say she`s the bestfondler ever."
Nicki - who has denied she is gay, but said on many occasions she finds women beautiful - also said one of the best moments of her career to date came when model Amber Rose convinced her then-boyfriend Kanye West to get her to appear on his track `Monster`.
She explained: "I was great friends with Amber Rose when they were dating and she had recommended me to him for his album and I guess he finally relented.
One day I got a call from her and she said Kanye wanted me to come down to Hawaii and record for the album.
"He`s become my mentor, he gives me advice, he hits me. He`s really into fashion so he`s a good person to have a well-rounded conversation with."
