Jenelle Evans' Bold New Hair Is a Total Blast From the Past (PHOTO)

Blondes have more fun! At least that seems to be the consensus with Jenelle Evans, who lightened up her hair just prior to leaving for vacation with her boyfriend and baby daddy Nathan Griffith.

The Teen Mom 2 star took to Instagram on Monday, January 5, to show off her new sun-kissed look.

Someone's blonder! ðï¿½ï¿½ï¿½

It's almost weird to see Jenelle with blonder hair again! She's been rocking a darker look for awhile now, and we can't help but wonder what made her decide to go back to the lighter hair we associate with her hard-partying days.

We're guessing that the reality star just wanted to lighten up for vacation. She and Nathan are heading to St. Thomas, and who doesn't want to look their best while sunbathing in some tropical rays?

Jenelle's been getting ready for this trip for awhile -- even drastically slimming her waistline -- so new hair just makes sense. Especially if she's hoping for Nathan to pop the question. She's been sharing tons of ring pictures on Twitter, so it's obviously on her mind.

What girl wouldn't want to look her absolute best when her man finally decides to put a ring on it?

Do you like Jenelle's new look?
