Amber Portwood Is Sporting A Brand-New Hair Color

The 'Teen Mom OG' cast member is no longer a brunette!

The old saying goes "blondes have more fun" -- and it seems that Amber Portwood is trying this motto on for size.

The "Teen Mom OG" cast member -- who rocked some magenta and burgundy tresses during last season of the long-running MTV series -- just changed up her hue and posted a Twitpic of her fresh look.

"Time for something new...my goodness I look tired though," Leah's mama added along with the sultry selfie above, showcasing her lightened-up long locks. We're going to have to disagree with the exhaustion-related statement and say she looks stellar -- and the 'do really brings out those baby blues.

But that's not the only physical change for Amber: The Indiana native recently gushed about a recent makeover milestone.

"36 lbs down and 15 more to go...almost at my goal," the "Never Too Late" author shared last month.
