The M-Train is officially back in motion: Meghan Trainor teased a brand new single on Instagram, and her next track is shaping up to be a decisively feminine affair.

Trainor, whose last album Thank You dropped in 2016, shared a pair of photos and a video that collectively pointed to the release of a track called "I'm a Lady" that's due out Friday (February 24). In one image, the newly blond Trainor gets coiffed by a stylist, and in a corresponding video, she — suddenly sporting a high hat — waits between music video takes as someone behind the camera observes "Wow, she looks amazing."

Finally, in a third image, a double-bunned Trainor presides over a boardroom at which women, exclusively, are seated. "I'm pretty cute and pretty smart," Trainor captioned the shot.

"Yaaaaaas finally oh god please let me be alive till that day," one Instagram follower wrote while another noted "YASSS IVE BEEN WAITING FOR SO LONG."

Trainor told the team behind Kiis FM's Jingle Ball in December 2016 that "I'm a Lady" — which will be featured on the Smurfs: The Lost Village soundtrack — is a "love yourself women anthem" that's "pretty fire."
