Mariah and publicist Cindi Berger

Songbird Mariah Carey is disputing reports that her former publicist, Cindi Berger, dumped Mariah as her client of 15 years because of her nasty attitude.

In a press release sent out by Mariah’s new manager, Stella Bulochnikov, Mariah said she dumped Berger first because her career was at a standstill and she wanted to go in a new direction.

Mariah’s new rep says Mariah sent Berger a polite letter severing all professional ties.

Mariah wrote in the letter, “I’ve done a lot of soul-searching this past year … and I found myself asking if I was truly employing a healthy perspective (not to sound too Oprah about it all :).”

She continued: “So I think it’s time for us to take a break Cindi,” saying she wants to “bring a fresh approach to this new phase in my career.”

In her letter, Mariah even offered to take out a full page ad in a Hollywood trade magazine, praising Berger and congratulating her on winning “Women of Power” award.

But gossip tabloid TMZ reached out to Berger’s peeps who claim she never got that letter.

According to the gossip rags, Berger cut ties with Mariah first because of her infamous attitude.

Sources say Berger, who also reps Rosie O’Donnell and Whoopi Goldberg, was simply too busy with her other bold name clients to drop what she was doing and tend to Mariah’s needs.

Mariah’s temper also, allegedly, sent her estranged husband, Nick Cannon, running for the hills.
