Shania Twain was quick to respond to the Supreme Court's decision on DOMA on Wednesday (June 26). The country superstar tweeted her support for the decision, saying, "Love is love."

In a 5-4 ruling, the Supreme Court found the Defense of Marriage Act unconstitutional. Signed into law by President Bill Clinton in 1996, DOMA prevented same-sex married couples from receiving hundreds of benefits available to married couples under federal law, even if they lived in states where same-sex marriage had been recognized.

"The federal statute is invalid, for no legitimate purpose overcomes the purpose and effect to disparage and to injure those whom the State, by its marriage laws, sought to protect in personhood and dignity,” Justice Anthony Kennedy wrote in the majority opinion. "By seeking to displace this protection and treating those persons as living in marriages less respected than others, the federal statute is in violation of the Fifth Amendment."

Carrie Underwood as one of the very few country stars who have spoken out in support of same-sex rights -- a hot-button topic in the decidedly conservative-leaning world of country music.

Country singer Chely Wright -- who became the genre's first openly gay star in 2010 and married her partner, Lauren Blitzer, in 2011 -- also reacted to the news, posting to Twitter, "Today is a huge day. Please let it be a day that bends mightily toward justice, equality and love."
