Bristol Palin To Replace Farrah Abraham On Teen Mom OG

Oh baby, baby.

In a sentence we never expected to write, Bristol Palin is joining MTV's Teen Mom OG for its next season.

She'll replace Farrah Abraham, who was fired by MTV last year.

Bristol Palin -- who is now 27 but was 17 when she gave birth to her first child Tripp -- is best known for being the daughter of former Republican vice presidential candidate Sarah Palin.

She'll be joining Teen Mom OG castmates Maci Bookout, Catelynn and Tyler Baltierra, and Amber Portwood as they continue to film the ups and downs of life after a teenage pregnancy. Also joining the cast this season is Mackenzie McKee from the short-lived Teen Mom 3.

Bristol has three children, one with ex-fiancé Levi Johnson and two with her estranged husband, Dakota Meyer. It will be her third outing as a reality star, after competing on Dancing With The Stars and appearing in her own Lifetime reality show Bristol Palin: Life’s a Tripp in 2012.

She also dipped her toe in the acting pool briefly in 2010 with a short stint on drama The Secret Life Of The American Teenager, where she played a teen mother-to-be.

For what it's worth, Farrah -- who settled a wrongful termination lawsuit with MTV after alleging that they fired her for her involvement in the adult film industry -- is unbothered by the news.

Speaking to Us Weekly, Farrah said: “Who cares!"

"Sorry I’m dealing with a family loss right now,” she added, referring to the death of her Pomeranian dog, Blue.

“I don’t care as there’s no replacement for me, as we all know,” she finished.

True that.

Meanwhile, Teen Mom 2 star Kailyn Lowry is a little shook by the news:

As for US????? Well, we think Farrah summed it up best when she said:
