Over the past few years, the call for marriage equality among musicians has into a deafening one, with everyone from Jay-Z and Beyonce to A$AP Rocky publicly declaring their support for same-sex marriage. And after the Supreme Court's historic ruling on Wednesday (June 26) -- one that overturned two laws restricting the rights of same-sex couples -- that noise erupted into gleeful applause.

Marking the biggest win for civil rights in decades, the Supreme Court's decision ruled unconstitutional the Defense of Marriage Act (DOMA) and California's Proposition 8. Under DOMA, the federal definition of marriage was restricted to different-sex couples, and Prop 8 had put a statewide ban on gay marriage in California.

And seeing as Hollywood is nestled in the Golden State and a large majority of musicians call California home, A-list celebrities were quick to show just how proud they were of their state -- and their nation.

Lady Gaga, meanwhile, shared a wedding photo of sorts to profess her excitement, adding, "We stand tall today.#DomaStruckDown So many fought for so long. Be proud, the prejudice are now the minority."

And Demi Lovato quickly reiterated President Barack Obama's declaration that "#LoveIsLove" when she tweeted, "Gay, straight, lesbian, bi.. No one is better than any one else. What an incredible day for California AND for equality."

Nick Jonas proclaimed he was "so proud to be an American," while Backstreet Boy Nick Carter put out a direct shout-out to the Supreme Court: "Congratulations on the Supreme Court ruling in California. You deserve it!"

Nickelodeon star Ariana Grande praised God and Cali for paving the way for marriage equality, writing, "Praise the Lord! Thank you California I am so proud live in a state where people are free to love & marry whoever they want. #equality #LOVE."

Openly gay "American Idol" alum Adam Lambert was also quick to show just how proud he was of his country, writing, "Down w DOMA! Something to be very proud of this upcoming July 4th. We are making beautiful progress for Equality! #proud." And Ricky Martin, who is also out, was equally ecstatic: "#PROP8 IS GONE! #DOMA IS GONE! #SCOTUS #LoveIsLove"

MTV BFF's Snooki and JWoww took to social media to express their support of the ruling: "So happy for #equality #loveislove !! My friends deserve THE BEST," Snooki tweeted. JWoww celebrated by retweeting President Obama, and Snooki also instagrammed a photo with someone holding a handwritten sign reading, "It's about time! Equal means equal."

Perhaps one of the loudest voices in the fight for gay marriage -- and one of the only ones in hip-hop -- is Macklemore, whose hit "Same Love" calls on listeners to accept love in all forms. Just last year, the Seattle-bred rapper talked to MTV News about how the track was a direct response to MCs who have encouraged homophobic views. "There is an epidemic of young people who are discovering their sexuality and are oppressed by it, " he told us. "I just try to take my personal experience and put it into a song."

One of those rappers who has constantly come under fire for seemingly homophobic lyrics is Odd Future leader Tyler, the Creator. But following the Supreme Court's decision, the MC seemed thrilled by the prospect of marriage for all, writing, "DOMA's Demise Hell Yuh."

And much like Brad Pitt and Angelina Jolie publicly declared, Kristen Bell and Dax Shepard vowed they would not get married until everyone had the opportunity to wed. So as soon as the good news traveled West from Washington, the actress was so excited she suggested she and her longtime boyfriend really celebrate: ".@daxshepard1 will you marry me? Xo #marriageequality #loveislove."

Your move, Brangelina.
