Lea Michelehas teased a clip of the video for her debut solo single, Cannonball.

“My video for #Cannonball premieres tomorrow on Entertainment Tonight and VEVO at 730ET!!! #24hourstogo,” she captioned the Instagram video.

In the 15-second snippet, the petite brunette sings into the camera while wearing a black gown.

No one else appears to accompany her in the vid for the track, which is apparently about “new beginnings”.

The actress, who found fame on the musical show about a school singing club, recently lost boyfriend and Glee co-star Cory Monteith over the summer.

Lea credits Cannonball, which was written by Sia, for helping her through the very dark period she experienced immediately following his death: “The minute I heard the song, it lifted me up. It picked me up from everything,” she said.

Her forthcoming debut, Louder, which is set to be released next month, also apparently features a song she wrote about the actor.
