Kim Kardashian Serenaded By Boyfriend

Kim Kardashian's boyfriend serenades her with her new song.

The reality TV star recently debuted her first single, 'Jam (Turn It Up)' and says NBA player Kris Humphries is such a fan, he is always singing it to her when they're on the phone.

She said: "Kris loves it. He sings it to me on the phone."

Kim - who is giving all her profits from the single to St. Jude's Children's Research Hospital - says she did the song to bring her out of her comfort zone and while she enjoyed it, she has no plans to release an album.

She told People magazine: "It was just something I tried. I don't have an album in the works. It was just something that kind of got me out of my comfort zone. And I'm really happy I went for it and did something I'm so not comfortable doing."
