Lady Gaga wrapped a tour with Tony Bennett this weekend in Washington, where she surprised him with a monstrous birthday cake and an audience sing-along to celebrate the final show.

But that was Saturday. Today, it’s time for new music.

In an Instagram post today, Gaga shared a selfie with the simple caption “LG5 Time.”

Not counting her Cheek To Cheek collaboration with Bennett, which featured a selection of jazz standards,  Lady Gaga has released four studio albums.

So little monsters everywhere are hoping “LG5” is code for a fifth studio album from Mother Monster.
