Have you heard the wonderful news? The state of Illinois has passed a same sex marriage bill, which means gay couples can officially tie the knot! This is an amazing and important step towards equal rights, and Teen Mom's Catelynn Lowell couldn't be happier. This starlet has long been a champion of LGBT rights (she even posed for the NOH8 campaign), and she took it to Instagram to voice her excitement about Illinois' new bill.

"Congratulations to everyone in Illinois!!!" Catelynn posted to Instagram. "My friends deserve to love and marry whoever they want. #equality #forall."

Amen to that. Catelynn's friends definitely deserve to love and marry whoever they want, and we're so happy that she took it to the internet to post her opinion, which — let's face it — is still somewhat controversial.

Even Catelynn's Instagram post is peppered with people who oppose gay marriage, however most of this gal's Teen Mom co-stars are right there with her. Like Catelynn, Teen Mom's Maci Bookout, Chelsea Houska, and Kailyn Lowry have voiced their support for gay marriage and posed for NOH8, and their outspoken opinion has doubtlessly influenced many fans to support gay marriage legislation!

What do you think of Catelynn's commitment to marriage equality? Hit the comments and tell us your thoughts about Illinois' new legislation!
