Bride-to-be Kim Kardashian is lightening up.

The reality star, 30, dyed her dark raven locks a light-brown shade, and premiered the look earlier this week in Studio City, Calif.

"I dyed my hair lighter for summer," the Keeping Up With the Kardashians star Tweeted. Her review? "I'm loving it! I feel younger!"

It's not the first time Kardashian has left the dark side: She tried out a blonde look after her first split with Reggie Bush in July 2009.

No word yet on whether the chestnut hue will stick around for Kardashian's wedding to NBA hunk Kris Humphries.
