Britney gets her old manager back, plus her Top 10 mistakes ever!

Frank Micelotta/Getty Images EntertainmentAfter a downward spiral of depressing events both professionally and personally, Britney Spears is slowly climbing back up the ladder with a successful TV appearance on How I Met Your Mother, and offers from 30 Rock and PETA. And now there is more good news: she is rekindling her working relationship with former manager Larry Rudolph. For those of you who don't know, he's the guy Britney's parents turned to in convincing her to enter rehab, so we're clearly into this guy. Though Britney and Larry have a bumpy history together, they have now made nice and she is enlisting his help for her comeback. This got us to thinking... if only Ms. Spears could take back the other mistakes she's made along the way. [OK!]

Behold, the Top 10 regrettable flubs of Britney in chronological order:

10) October 2007 - The girl who back in 2001 had the highest debut week album sales by any solo artist (1.3 million for Oops…I did it Again) releases her fifth album, Blackout to mediocre sales and reviews.

9) September 2007 - With a new album about to debut, Britney tries to prove she's still got it with a performance of her new single, "Gimme More" at the MTV VMA's. We think her choreography will surely shut people up. But alas, her poor attempt at lip-syncing and limp movements match her great-but-not-what-they-once-were abs and the act is sheer agony to watch.

8) February 2007 - Britney gets two tattoos and shaves her head. We refuse to believe it's true and pray that with her hair she has shed anything and everything "Toxic" from her system. Spears checks herself into rehab.

7) November 2006 - After divorcing K-Fed, Britney goes on a partying rampage, smoking heavily and taking clothes off in clubs. She's often photographed sans panties. Ughhh…

6) June 2006 - The Dateline interview with Matt Lauer. Spears dressed herself in too-short cutoffs, horribly applied false lashes and chewed gum the whole time. What was meant to clear her image, only made her look like an "emotional wreck."

5) February 2006 - Driving with 4-month-old son Sean Preston in her lap instead of a car seat, prompting authorities to investigate a slew of events that peg Britney as a bad a mom.

4) May 2005 - The reality show Britney and Kevin: Chaotic debuts on TV, giving a depressing glimpse into the lives of the couple that we wish we'd never seen.

3) September 2004 - Britney marries backup dancer Kevin Federline, who already has two kids with actress Shar Jackson. We know he's looking not so bad now, but imagine how things could have gone down if he never entered the picture.

2) January 2004 - Britney's shotgun wedding to childhood pal Jason Allen Alexander at Las Vegas' Little White Wedding Chapel. The 55-hour marriage wasn't worth it. People started to think she was crazy.

1) December 2002 - Justin Timberlake's video for "Cry Me a River" debuts. The couple had split back in March, but secretly we had hopes for a reunion, despite rumors of infidelity. The breakup marks the end of an era and breaks our hearts-WHY?
