GOOD • Almost all of her albums contain at least one great dance-floor smash.
• She always gets herself in shape for hot videos and fab photo shoots.
• She prudently launched her 2008 comeback with a TV sitcom gig, playing a receptionist on CBS' "How I Met Your Mother."

BAD • After a New Year's weekend of partying in Las Vegas, she married a high school friend in 2004, then had it annulled.
• Wearing only panties, she locked herself in a bathroom with son Jayden for three hours, and argued with an officer who tried to give her a sweater.
• In 2007, she checked out of a rehab center less than 24 hours after checking in, went to a salon and shaved her head.
• Dressed like a hooker with a cheap hair-weave, she gave a narcoleptic performance of "Gimme More" on the 2007 MTV Video Music Awards.
