Britney Spears is a woman who knows what she likes and commits to it, at least when it comes to fashion.

In a span of six days, the 31-year-old pop star wore three variations of the same outfit while out and about in Los Angeles.

It's stylish, versatile, and the Hollywood hair trend du jour … ladies and gentlemen, behold the new bob!

Christina Hendricks, Jennifer Lawrence, Julianne Hough, and Nikki Reed are just a few of the beauties who've chopped off their locks into a shorter -- but not so short that it's shocking -- bob style in recent weeks.

"The long bob, or 'lob' as it is more commonly called, is currently one of the most requested cuts in salons around the country," says Julia Papworth, an L.A. hairdresser and makeup artist whose celebrity clients have included Emma Roberts and Kendra Wilkinson.

Just days after Justin Bieber tweeted a photo of the twosome cozied up (sparking rumors that they may have gotten back together), even sexier images of Selena Gomez hit the Internet — from her new Adidas NEO campaign, that is. From the looks of the shoot, one thing is certain: whether she's single or not, this girl is all grow'd up.

In the pics, the 20-year-old "Spring Breakers" star pairs the sporty sneaks with barely-there shorts and knee-high socks, the occasional pair of skintight jeans, smoldering eyes, and tousled hair. In other words, she's pretty much every guy's dream girl. Her poses vary between somewhat playful (blowing bubbles) to downright seductive (perched on a wall with a come-hither stare).

Miley "Can't Be Tamed" Cyrus regularly raises eyebrows with her fashion choices.

Her cutoff shorts, high-waisted jeans, and ab-baring tops are often called into question. But recently, the 20-year-old wore something that had already earned the celebrity seal of approval -- the same garment that model-turned-actress Rosie Huntington-Whiteley, 26, had sported a month before.
