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. "
