Finally!!!!

The good news: TMZ.com is reporting that Britney Spears has checked into rehab.

The bad news: She checked out in less than 24 hours!

The Britster reportedly checked herself in with the urging of her friends and family, then refused to stay. The facility she was in is not in this country.

The AP is reporting that she just checked in an hour ago...guess the party is over. Perfect timing though, I don't think she could make it through another weekend of hard partying.Spears was last seen leaving New York City four nights ago on a private jet with her two young sons heading to Miami.

Then, she disappeared off the paparazzi radar.

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.

"Ruben,'' who runs ThatOtherBlog, told The Associated Press today 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.''
