We've seen Fringe's Anna Torv naked; now see her sing!

Remember that musical episode of Fox's sci-fi series Fringe we told you about? Fox has released more details.

The episode, called "Brown Betty" (not "Overture," as we were previously told), will air April 29 as part of Fox's Glee-themed programming lineup, "Fox Rocks." Here's the official description:

Thursday, April 29 FRINGE (9:00-10:00 PM ET/PT) - "Brown Betty" While Walter (John Noble) deals with some upsetting news, he tells Olivia's niece, Ella (guest star Lily Pilblad), a fairy tale that includes musical performances by Olivia (Anna Torv) and Agent Broyles (Lance Reddick).

We can't wait to see Torv singing, not to mention Reddick.

Fringe airs Thursdays at 9 p.m. ET/PT.
