Courtney Stodden Sizzles in Bikini For New Hair Style Debut

Courtney Stodden is making some big changes three weeks into a new year ... and, you guessed it, it's a cosmetic one.

The influencer hopped on social media Friday and posted a thirst trap of her in a skimpy bikini on the beach, showing off her new feature ... dark hair.

Waiting for your permission to load the Instagram Media.

Courtney's mostly been blonde since she's been a public figure ... but she's switched things up here and gone many shades darker.

She captioned the snap, "New year! New hair!"

The hair color is different, but Courtney's sex appeal remains unchanged ... she knows how to command attention and fish for compliments.

Courtney also shared the post on her Instagram Story and added some music ... going with Rihanna's "Kiss it Better."

Who says blondes are the only ones who can have fun?!?
