With a plan on how to implement repeal of “Don't Ask, Don't Tell” to be unveiled on Friday, we offer a flashback of celebrity views on the subject.

Celebrities rejoiced last month when Congress repealed the 17-year-old law that bans gay and bisexual troops from serving openly.

“Can't hold back the tears+pride,” pop star Lady Gaga tweeted to her more than 7 million followers. “We did it! Our voice was heard + today the Senate REPEALED DADT. A triumph for equality after 17 YEARS.”

The Alejandro singer had mounted a spirited campaign to end the law. Her efforts made her the most visible celebrity to advocate for repeal.

Singer Ricky Martin, who recently announced he's gay, tweeted: “One step closer to #equality!! #DADT is gone!”

“So proud of Congress for making the right decision,” Neil Patrick Harris, who recently became a dad, tweeted. “Now all soldiers can serve with integrity. A gr8 day.”

“It's passe and old-fashioned,” rocker Adam Lambert told iReport blogger Chris Morrow at last year's Gay & Lesbian Alliance Against Defamation (GLAAD) Media Awards in Los Angeles.

Skating champ Johnny Weir, who has denied being a gay activist, had a lot to say on the subject.

“I think it doesn't matter what somebody is,” Weir said. “I think it matters who they are. And that's something that I stand by very firmly. I mean, if you want to fight in the military, God bless you. We need more heroes in this world. Whether you're gay or straight it doesn't matter, you're fighting for this country.”
