Late on Friday, New York became the sixth (and most populous) state in the nation to pass a law allowing gay marriage, and in celebration, stars joined supporters of the measure to cheer the historic milestone on Twitter.

Pink gave an all-caps jump for joy, shouting, "CONGRATULATIONS!!!!! ABOUT TIME!"

Neil Patrick Harris tweeted, "It PASSED! Marriage equality in NY!! Yes!! Progress!! Thank you everyone who worked so hard on this!! A historic night!" His elated partner, David Burtka, announced, "I've already proposed, he said yes! Thank god!" (He soon added a clarification: "Neil and I have been wearing rings for years. We have been engaged for a while. It did not just happen.")

Russell Simmons, who gave counsel to Tracy Morgan during the comic's recent homophobia controversy, logged on to tweet, "I applaud the work of our state gov't and all of the advocates on tonight's vote to legalize same sex marriage." He added, "The rights u take for granted are only valid if u fight to give those same rights to others."

Lady Gaga said, "I can't stop crying. We did it kids."

New Yorkers Alec Baldwin and Rosie O'Donnell joined the online praise; he tweeted, " Cynthia Nixon for all of her hard work on behalf of marriage equality" while O'Donnell wrote, "Happy gays r here again!!!!!"

LeAnn Rimes celebrated with the tweet, "Hell yeah NY! I have gotten several requests from friends....for a wedding singer!!!"
