NEW YORK - An e-mail from Britney Spears' former assistant Felicia Culotta saying the 25-year-old pop star needs to get her act together because she's headed for "rock bottom" has been posted on a Web site's gossip blog.

"I cherish ALL the incredible opportunities that came my way thru my job with Britney and am crushed/saddened/heart sick by the way her life is unfolding," says the e-mail, posted this week on ThatOtherBlog, a gossip blog on the Hollywood.com Web site.

The e-mail, addressed to "Ruben," was sent in response to an editorial "Why Britney Is Asking for It," according to the blog.

"I want you to know Ruben that WE (as in her Family and nearest and dearest -- ALL of whom are not on the payroll anymore!!) are doing EVERYTHING in our power to get help for Britney," writes Culotta, who says she worked for Spears for nearly 10 years.

Since filing for divorce from Kevin Federline in November, Spears has drawn criticism for her drinking, partying and sloppy appearance.

"Ruben," who runs ThatOtherBlog, told The Associated Press on Friday that Culotta is a good friend and that he is declining media requests to interview her. In her e-mail, Culotta said she is working as a corporate flight attendant and living in Mississippi.

Gina Orr, Spears' publicist at Jive Records, couldn't be reached at her office Friday and didn't immediately respond to an e-mail from the AP asking for comment.

"There's just so much you can do to help a person -- I don't dare want to be an enabler, and I cannot love her enough for the both of us," Culotta says.

"I cannot convince her in ANY way to love herself. ... I cannot save her from herself, nor can I commit her to any type of treatment program against her wishes and will."

Culotta says Spears' friends are doing "all in our power to NOT pad the bottom or move the bottom, so when she does indeed hit rock bottom, she'll stand up and walk away from this whole fiasco a new, confident, changed, career driven Britney like we all knew and loved."
