Heidi Montag - Heidi Montag Quits Tv Show

Heidi Montag has dropped out of starring in a reality TV show with her best friend.

The blonde star had planned to appear in a series with her 'Hills' co-star Jennifer Bunney after moving in to her Malibu home this summer.

But Jennifer has revealed on her blog: "Originally I was supposed to do a reality show with Heidi , but right now it looks like some things have changed."

She has denied the pair have had a bust-up and claims Heidi has simply changed her mind - saying she doesn't know if she "wants to be in a reality TV series at the moment with everything going on in her personal life".

She added: "No we are not in a fight and no Heidi is not 'dropping' me to do reality shows with the twins."

Heidi - who has had multiple plastic surgery procedures - had been rumoured to be planning a show with Hugh Hefner's ex-girlfriends, twins Kristina and Karissa Shannon.

The star had also talked about launching a music career after having the "best summer" of her life following her split from her husband Spencer Pratt.

She has been working on a second album with Steve Morales - who has previously worked on records with Destiny's Child and Christina Aguilera.

Disappointed Jennifer, meanwhile, says her reality TV show is still going to air in January despite Heidi dropping out.

She said: "Although I wanted to do this project with her, I also respect that she has a lot to deal with right now and have to decided to go ahead and move forward with it alone. My hope is that she will want to be involved later on."
