You're move, Jack Antonoff. The Bleachers lead singer and his longtime girlfriend Lena Dunham have been vocal about not tying the knot until gay marriage was legalized in all 50 states. Well, guess what happened on June 26!

And Lena wasted no time nudging her man.

".@jackantonoff Get on it, yo…" she tweeted after the U.S. Supreme Court legalized same-sex marriage.

Jack seems to have gotten the hint, even "favoriting" the tweet and writing several messages in full support of the high court's decision.

"Gonna tweet something I never thought I would: !!!!!!!!!!!!! USA USA USA USA !!!!!!!!!!!!!!!!" he tweeted, later saying, "So many amazing people worked tirelessly for decades for this. in awe of them today and always."

Lena, too, applauded the decision, writing, "Let's use this victory as a reminder to keep pushing for equality on every frontier. We have the power!"

If Lena gets her way, they'll both be writing something else: their names on a marriage license!
