Is Lea Michele
preparing to walk down the aisle?
Not in real life, but on Monday the actress, 25, posted a photo of herself wearing a wedding gown surrounded by her costars in bridesmaid dresses, hinting at what could be to come on Glee
's winter finale Tuesday night.
"In anticipation of tomorrow's very memorable episode, we took this photo," Michele Tweeted Monday
, accompanied by the shot that looks like the poster for the hit movie Bridesmaids
. "We call it GLEE-MAIDS."
Michele's character, Rachel Berry, and Cory Monteith
's character, Finn Hudson, are engaged on the show, but there's no official word on whether an actual wedding – or perhaps just a dream sequence – takes place during the episode.
The photo includes Amber Riley, Vanessa Lengies, Jenna Ushkowitz, Heather Morris and Naya Rivera. Dianna Agron is presumably absent from the shot because her character, Quinn Fabray, disapproves of Rachel and Finn's plans to wed so young.
