Gay Rights Ruling: Celebs React on Twitter to Supreme Court Striking Down Defense of Marriage Act

Lena Dunham, Alyssa Milano, Ben Affleck, Jesse Tyler Ferguson among celebs weighing in on today's historic ruling in favor of gay marriage

Hollywood is applauding the United States Supreme Court.

In two 5-4 rulings on Wednesday, the high court dismissed a defense of Proposition 8, the 2008 ballot measure in California that outlawed same-sex marriage, and determined that the federal Defense of Marriage Act, signed by President Bill Clinton in 1996, is unconstitutional.

The verdict is not only a huge victory for gay rights activists who sued to ensure same-sex spouses are entitled to federal benefits and equal protection under the law, but it's a cause for celebration among celebrities who for years have been advocating for the court to overturn DOMA.

Here's a roundup of stars' reactions on Twitter:

Jesse Tyler Ferguson: "Victory for marriage in California as #Prop8 is struck down. Small but substantial steps toward #MarriageEquality for all!"

Ben Affleck: "Big news from the Supreme Court. Goodbye #DOMA #Prop8. Hello #equality."

Kal Penn: "#DOMA decision is based on equal protection/5th amendment, not states rights. That's a great distinction. #skeet #skeet #skeet @SCOTUSblog"
