Heidi Montag has dropped out of starring in a new reality TV show with her bestie.

The former ‘Hills’ star had planned to appear in a series with co-star Jennifer Bunney after moving in to her Malibu pad this summer.

But Bunney 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.”

Bunney denies the pair have fallen out, with claims Montag 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.”

Montag – famousy as a star in the hit MTV reality show, as well as her multiple plastic surgery procedures – is rumoured to be planning a show with Hugh Hefner’s ex-girlfriends, twins Kristina and Karissa Shannon (tits TV galore!!).

The star had also talked about launching a muzak career after having the “best summer” of her life following her split from her hubby and all-round w*nker, Spencer ‘the’ Pratt.

She has been working on a second album with Steve Morales - who has previously produced tracks for soul diva’s Destiny’s Child and X-tina (Christina Aguilera).

Bunney, meanwhile, says the reality TV show is still going to air in January despite Montag 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.”

Will anyone watch, we doubt it. We feel a ‘TV bomb’ coming on!
