Heidi Montag has fired her manager just a week after hiring him.

The reality TV star has announced she will now be in charge of her career after parting ways with Malibu psychic Aiden Chase, who worked as her "intuitive healer" for a month after her 10 plastic surgeries in one day last year.

She said: "I have decided to part ways with Mr. Chase both as a manager and as a psychic and will scrutinise my business decisions more carefully in the future. I will now be managing my own career as a strong and independent woman."

Heidi hired Aiden after sacking husband Spender Pratt - who had been her business manager for five years - but says she decided to end their working relationship after being left unimpressed with his behaviour as she filmed movie 'Just Go With It' and reality TV show 'The Hills'.

She told people.com: "Unfortunately recent behaviour by Mr. Chase on set of both 'Just Go With It' starring Adam Sandler, Jennifer Aniston and Nicole Kidman and on 'The Hills' have made me question this decision."

Aiden responded: "At this time, I am not aware of any change in my business relationship with Heidi Montag."
