Adam Lambert, Jane Lynch, Neil Patrick Harris and Adam Levine are among the celebrities cheering President Barack Obama's gay marriage support.

Obama on Wednesday told ABC News' Robin Roberts: “I've concluded that for me personally it is important for me to go ahead and affirm that I think same sex couples should be able to get married.”

The news quickly went viral on social networks.

“Yes!” Lambert messaged on Twitter. “Of course I am completely in support of gay marriage. I also have an amazing boyfriend. This doesn't mean I'm getting married. Lol!”

Glee's Jane Lynch, who married her girlfriend in 2010, tweeted: “Obama: Marriage? Gay is okay!”

“Pretty darn happy today,” she followed up. “Thanks Mr President, for supporting the dignity of my family and so many others!”

The Voice judge Adam Levine messaged: “thank you @BarackObama for reminding us all that true leadership is not dead.”

“@BarackObama: President Obama announces his support for same-sex marriage,” Neil Patrick Harris tweeted. “Bravo, Mr. President, and thank you.”

Lady Gaga, Alec Baldwin, Tyra Banks, Josh Groban, Samantha Ronson, Ricky Martin, Chris Colfer, Cyndi Lauper and Ellen DeGerenes have also cheered on the president.
