Santana Lopez, played by Naya Rivera.
The only known lesbian on Glee is Santana Lopez. Whilst Brittany S. Pierce is often thought of as a lesbian too, it was confirmed that Brittany is actually bisexual instead.
Neither the character, Rachel Berry, nor the actor who portrays her, Lea Michele, are (is?) lesbian.
Yes. She admits she is in the episode sexy of glee. She is in love with Brittany. But to her dismay Brittany is still in love with Ardie.
None yet, but she has been signed on to play Kurt's lesbian aunt in a later episode.
She's straight in real life, but she played the role of a lesbian aunt of Kurt on Glee. It was only acting, though.
No Yes there is. She was in an interview for the Glee Project saying how when she was younger she started to realize that she liked girls, and when she came out to her parents at 16, they were fine with it.
