Heidi Montag talks about making music almost as much as she talks about the feud with her Hills costar Lauren Conrad. But unlike her very public fights, Montag did not want a song she recorded to be played on the air.
Touted as the "world premiere" of Montag's single, Ryan Seacrest played a song called "Body Language" on his KISS-FM radio show on Thursday. But the track, which takes a beat from Yaz's "Situation" and features Montag's fiancé and manager Spencer Pratt as a rapper, wasn't supposed to be released, according to Pratt.
"We did it as a joke," Pratt tells PEOPLE. "It's not her single at all. It was never meant to be heard by anyone but us. Over my dead body would I rap on Heidi's first single. Heidi is so upset because this was not the first sound she wanted people to hear from her."
What is Montag's sound? "It's very dance, urban, rhythmical," she told Seacrest during a recent radio appearance. "But I really love a lot of rap and urban music at the same time so I'm kind of bringing a little bit of those elements in."
When it comes to the couple's engagement, Montag's music career takes precedent. "I am shopping [for a dress]," she told PEOPLE at the season three premiere of The Hills. "But we haven't done anything [else], we're just so busy in the studio and with my music we don't really have time to plan a wedding."
And for those who didn't hear it, the song (it's bracketed by Ryan Seacrest talking, so skip to about 1:15 in.
