Brooke Hogan Releases Heidi Montag Dis Track

With 'Ur Not That Hot,' Hogan causes many to wonder what sparked the reality star beef.

For whatever reason, there seems to be some kind of beef brewing between reality-TV stars Brooke Hogan and Heidi Montag. In a new song called "Ur Not That Hot" released on Wednesday, Hogan very blatantly disses Montag.

Hulk Hogan's daughter doesn't just metaphorically call out the "Hills" star. The track begins with someone impersonating Montag in a voicemail.

"Umm. Hey Brooke, what's up?" the Heidi-impersonator says. "This is Heidi Montag. I just want to let you know that I'm making a record and that your record ... better watch its back. And, if you think that Stack$ is awesome, just wait for Spencer. Bye."

The song features her rapper boyfriend Stack$ and will be on Hogan's album, Redemption, out next month. Before dropping the LP, Hogan is releasing a mixtape, Judgment Day, out on July 4, according to her Twitter.

On her MySpace blog, Hogan doesn't really explain why she's feuding with Montag. "WHY???? Because I can," she wrote. "And this is just the tip of the iceberg! I'm so sick of people that use me and my family, people with NO talent calling people out who work harder than them, and just people who have a dumbass attitude to begin with."

Calls to reps for Montag and Hogan were not returned to MTV News at press time, but in an e-mail to MTV News, Spencer Pratt responded to the song. "Is that the wrestler's daughter?" he wrote. "If so, Speidi will be praying for her and her family!"
