The CW has not only released the extended trailer for Supergirl's "Star-Crossed" episode -- which literally confirms what we've been suspecting all along -- but also the first footage and pics from the upcoming Flash/Supergirl musical crossover, revealing our first look at Darren Criss as Music Meister.

Who's up for a little song and dance?

First things first: Mon-El (Chris Wood) is the Prince of Daxam. I repeat, Mon-El is the Prince of Daxam. Moreover, Lois Lane (Lois & Clark: The New Adventures of Superman's Teri Hatcher) and Hercules (Kevin Sorbo) are indeed playing his parents, the King and Queen of Daxam, seen in the closing minutes of this week's episode. How awesome is that? Very awesome.

From the look of things, the reveal of Mon-El's secret is going to put a spanner in the growing relationship between star-crossed (pun totally intended) lovers Kara (Melissa Benoist) and Mon-El. Here's the episode synopsis:

A new villain (guest star Teri Hatcher) comes to National City, putting Supergirl (Melissa Benoist) on high alert. Meanwhile, Winn's (Jeremy Jordan) girlfriend, Lyra (guest star Tamzin Merchant), gets Winn in trouble with the law. Maggie (guest star Floriana Lima) attempts to help Winn but old loyalties get in the way. The Music Meister (Darren Criss) attacks Supergirl.

The Supergirl/Flash musical extravaganza kicks off with Supergirl's "Star-Crossed" on March 20 (there's no new episode next week) and concludes the following night on The Flash in an episode titled "Duet." Read up on the official synopsis before digging into the short teaser and the gallery of pics (via Coming Soon):

Barry (Grant Gustin) and team are surprised when Mon-El (guest star Chris Wood) and Hank Henshaw (guest star David Harewood) arrive on their Earth carrying a comatose Supergirl (guest star Melissa Benoist) who was whammied by the Music Meister (guest star Darren Criss). Unable to wake her up, they turn to Team Flash to save her. However, the Music Meister surprises The Flash and puts him in a similar coma, one that Team Flash can't cure. Kara and Barry wake up without their powers in an alternate reality where life is like a musical and the only way to escape is by following the script, complete with singing and dancing, to the end.

Supergirl airs Mondays (but not next Monday, March 13) at 8 p.m. and The Flash on Tuesdays at 8 p.m. on The CW.
