Katy Perry

Katy Perry's recent bob may or may not be an ode to her newly single life, but psych professor at Fairleigh Dickinson University, Judith Waters, says when it comes to a breakup makeover its important to find a new look that will fit your normal lifestyle.

Kim Kardashian

She was only married for 72 days, but it didn't take too long after filing the divorce papers before showing off a new look. Note to Kim: a new hairstyle with bangs won't make the world forget about your joke of a marriage.

Scarlett Johansson

"Looking good is the first, easiest and least expensive way to begin a program of personal rehabilitation," says Waters. ScarJo's bob after her divorce from Ryan Reynolds is a prime example of a sexy post-breakup look.

Olivia Wilde

Olivia Wilde and her hubby broke up in early 2011 and not long after she swapped her shiny locks for a bangin' new 'do.

Lauren Conrad

Lauren Conrad went through two big changes last summer: She broke up with her boyfriend, actor Kyle Howard, and she traded in her two-toned, sunkissed locks for light blue and silver highlights.

Lindsay Lohan

At first, we thought it was only Lindsay's career that was going down the tubes, but then we realized it was her overall hygiene that was deteriorating. We're hoping the money she made from Playboy will pay for a new set of veneers and some classes at the local community college so she can learn a new trade.

Angelina Jolie

It's not that we don't think Angelina Jolie is beautiful or that she doesn't do great charitable things, but does she have to wear the same tired look every time she's on a red carpet? This year, we're hoping a new stylist will come into Angie's life and teach her that dresses come in other colors besides black.

Jessica Simpson

Where do we even begin with this one? Being pregnant does not give celebrities license to wear loud animal prints and stop caring about their overall appearance. Not only has Jessica Simpson started wearing less makeup and more sweatpants, but she's even gone as far as tweeting a picture of her sitting on a public toilet. Dear God, please grant Jess some self-awareness this year!

Courtney Stodden

If you're not yet aware of who Courtney Stodden is, then we beg you to do some Googling. This is the 16-year-old bride of LOST actor, Doug Hutchinson and the latest sensation to take over gossip sites and magazines. We want Courtney to start dressing like a 16-year-old and stop dressing like a man who's trying to look like a 16-year-old.
