Hollywood's Biggest Comebacks

You can't keep a big star down! See the celebs – Paula, Ben, RDJ, Drew – who've resurfaced with extra shine

BRITNEY SPEARS

Though it's up for debate when, exactly, Spears began her slide, by 2007, the image of the recently shorn single mom attacking a paparazzo's car was a sure sign she was in serious trouble.
The comeback: Following a stint in rehab, Spears was placed in a conservatorship overseen by her father, and slowly allowed her star to rise again. In 2011, she embarked on a successful world tour, with a residency at Planet Hollywood in Las Vegas starting soon after.
