MTV Style Headlines Of The Week: Kristin Cavallari's Hair Changes, Lady Gaga's Male Alter Ego And More

Kristin Cavallari's lighter hair

• New looks emerged: Kristin Cavallari ditched her dark hair for lighter locks, but then later tweeted at us and said they just lightened naturally in the sun.

Lady Gaga will always be different! She wears nipple stickers when she flies, and she has a "male" alter ego named Jo Calderone.

• Blue eye makeup blew us away, from Stephanie Pratt's blue eyeliner to Hayley Williams of Paramore's eye shadow.

• Check out the fabulously dressed Rihanna and Ke$ha fans when The Last Girl On Earth Tour came to NYC.

Jared Leto of 30 Seconds To Mars rocked some awesome zebra print shades and white and pink facepaint.

• Nice skirts! Amber Lancaster went for black, while Reese Witherspoon and Olivia Palermo both went for the same orange watercolor print. Speaking of Olivia, she took a stab at modeling for Hogan, next to her boyfriend!

Drake + Suit + Skinny Tie = YUMMY. Need we say more? Speaking of guy fashion, watch Bruno Mars try to explain his hat obsession.

• All that glitters IS GOLD, like Jessica Alba's gorgeous Balmain frock, and Drew Barrymore and Mary J. Blige in Catherine Malandrino.

Britney the bride? She certainly looked wedding day ready on the cover of Pop magazine. But is that better than Katy Perry as a ballerina?

It's the last weekend in August — ALREADY! Time to soak up some sun and shop for fabulous fall outerwear. Happy weekend!
