The world may have to wait for the patter of little Speidi feet: Heidi Montag says that her quest to have kids with husband Spencer Pratt is "kind of on hold" as she launches her campaign to become a "pop star" with her just-released album Superficial.

"I`m really trying to do this pop star [thing], my first album, so I think that would kind of be distracting from this album coming out," she said in a radio interview with Ryan Seacrest Tuesday. "But one day I would love to have kids. I don`t know if Spencer quite feels the same way."

The Hills star spent three years working on Superficial, which features songs like "I`ll Do It," in which she tells a lover to "come eat my panties off of me." R-rated lyrics or not, she tells Seacrest that "it`s very personal, empowering music...just about living life and enjoying every moment and living it up--definitely club music."

The reality diva also explains the title. "I think that Superficial is kind of a double entendre," she says. "It`s superficial in a sense that everything in Hollywood is a little superficial. It`s superficial in a positive way too. It`s not what it seems to be, it`s the inside that counts. It`s kind of the unknown and the known."

On the spiritual side, Montag and Pratt "have been getting very into yoga," she says. "It`s very relaxing and has definitely calmed my husband down a little bit. He`s a little energetic. "
