According to various sources, Britney Spears has once again pulled a revolving door stint in rehab, checking into Malibu's Promise Center on Tuesday afternoon and bolting out the door as early as the following morning.

[Insert obligatory "Oops She Did It Again" joke.]

As we all know, Brit checked into rehab (again) yesterday, supposedly at the urging of her friends an family, after shaving her head this past weekend and making a 1-day cameo at an out-of-country rehab center last week.

And already the rumors are flying.

Amidst all this is she/isn't she rehabbing confusion, our inbox has been overwhelmed with a myriad of Brit-related updates:

• Brit only shaved her head after Kevin threatened to submit her damaged hair follicles to an involuntary drug-test! (Extra)
• But wait—maybe it was really because she had lice! (Daily Mail)
• Either way, Justin's calling Brit's new look a "smart choice!" (Tittle-Tattle Too)
• Also, Brit's burning through her cash supply because of her lackluster perfume sales and complete and utter lack of a career! (OK!)
• Plus, Brit's done coke! And ecstasy! In front of other people! (In Touch Weekly)
• And Brit hires nannies solely based on their personal lives, and their willingness to watch her strip down naked in front of them! (Us)

All of which make us kinda glad that Craig Ferguson has decided to take a one-man stand against Britney Shears jokes.

Update: TMZ is now reporting that Child Services' Hotline has been "blowing up" with calls about Britney Spears.
