It's the Reality Stars Battle Royale, with The Hills' Heidi Montag-Pratt against Brooke Knows Best's Brooke Hogan.  The feud began when the infamous wrestler's daughter released her latest single "Ur Not That Hot!" and blatantly dissed Montag in the lyrics.

The track begins with a stranger impersonating the Hills star in a voicemail.  "Umm. Hey Brooke, what's up?" the song 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 Hills stars Spencer and Heidi Pratt are never going to shut up unless extreme measures are taken.  This week, they became the point of controversy once again for commenting on several political issues during their appearance on Alex Jones' radio show.  Speidi spewed out remarks regarding 9/11, global warming and even President Obama.

It's possible that Spencer and Heidi wouldn't have discussed such issues if Jones didn't provoke them.  Known for his conspiracy theories, the host apparently rubbed off on the two reality stars.

While there have been numerous rumors of Audrina Patridge getting her own reality series, this time it's been confirmed.  The star will be leaving The Hills when it wraps up a sixth season and will be focusing on developing her own show at last.

According to Entertainment Weekly, the new program will be produced by Mark Burnett of Survivor and The Apprentice fame.  The solo project has also been tentatively called The Audrina Show and is currently under development at MTV.

These reality television stars have each other's backs.  Keeping Up with the Kardashians' Kim Kardashian was reportedly the one who told her friend, The Hills' Heidi Montag-Pratt, to pose for the magazine Playboy.  The wife of Spencer Pratt was hesitant to reveal the news at first, but it looks like the industry's abuzz with the matter.

Never one to keep such a great secret, Kim Kardashian told MTV News about her discussion with Heidi.  She's posed for Playboy before and even gave the newbie some advice on what to do.

Despite her stint on The Hills over and done with, Lauren Conrad is still the subject of numerous controversies.  She may have wanted to put all that behind her, but there's no doubt it's going to follow her everywhere.  On a recent appearance on The View, the reality TV starlet discussed her upcoming book.  However, she couldn't help comment on the rumor that's been plaguing her lately: the one about her alleged sex tape.

Even though she was brought over to introduce her novel, LA Candy, there were more pressing matters to attend to.  Talk show co-host Elisabeth Hasselback brought up the issue of Spencer Pratt's supposed apology, and suddenly caught the star off-guard.

She may be a new face on The Hills, but Kristin Cavallari has been around the reality TV circuit for quite some time now.  She's established herself in Laguna Beach as someone to look out for, especially because she's developed her own sense of style.

On a recent interview, the upcoming Hills star talked about who she looks up to in the industry in addition to giving advice to those who want to be like her.  Cavallari admitted that throughout the years, she's gone through a variety of fashions that others might enjoy.
