It's Monday, Monday, Monday ... and Rebecca Black's new single debuts tonight.

The 14-year-old singer -- whose music video "Friday" went kookoo-for-Cocoa Puffs online, racking up 167 million views thus far -- unveils a new song and video at 7 tonight on her official YouTube channel.

The song is called "My Moment" and chronicles Black's rise to fame, featuring clips from recent months of Black hosting MTV's O Music Awards and various TV appearances.

Black is currently finishing up a 5-track EP, due next month.

UPDATE: And here 'tis ...

... and, as expected, there's nothing here but a fluttery pair of eyelashes.
