We really didn't want to have to do this, but we feel obliged to inform you that Britney has reportedly signed up for her third round of rehab.

According to TMZ, Federline's emergency custody hearing has been temporarily postponed on the condition that Britney enrolls in—and completes—an inpatient rehab program scheduled to last between 30 and 45 days.

Federline is concerned for Spears' welfare and wants her to get the help she is now seeking. We're also told this will be Spears' last chance — if she leaves rehab before getting full treatment, Federline will immediately go to court seeking orders allowing him unquestioned full custody of the children.

Surprisingly, although the blogs have been in frenzied competition all week long to catalogue "Britney Shears" and her gradual descent into madness, they mostly had encouraging words for the obviously troubled former pop star:

• "Here’s hoping….third time’s a charm!" (Dlisted)
• "We all hope for the best for Britney, and wish that she is finally able and, more importantly, willing to get the help that she so desperately needs." (Popsugar)
• "We think Britney's gonna make it this time. We give her TWO days until she tries to escape rehab again!!! (PerezHilton)

Well, almost all the blogs were sympathetic. But, for what it's worth, we wish her the best.
