Earlier today it was announced that same-sex marriage was now legal across all 50 states of America and it seems like the whole world is celebrating!

"Today is a big step in our march toward equality," President Barack Obama tweeted on Friday. "Gay and lesbian couples now have the right to marry, just like anyone else. #LoveWins."

Many celebrities have tweeted their happiness at this decision which comes shortly after Ireland's marriage referendum.
