‘Glee’ star Jonathan Groff is Lea Michele’s ‘maid of honor’

Gleeks stay together.

Newly engaged Lea Michele revealed on Instagram on Wednesday that her former “Glee” co-star Jonathan Groff will be her “maid of honor” when she ties the knot with fashion exec Zandy Reich.

Groff, 33, played Jesse St. James on the hit show with Michele, 31, from 2010 to 2015. Prior to that, they starred together in the Broadway musical “Spring Awakening.”

Michele, who wrote on Instagram a week ago that she’s still on “cloud 9” after recently getting engaged to Reich, said on “Watch What Happens Live With Andy Cohen” that she didn’t initially believe her husband-to-be when he popped the question with a 4-carat rock.

“I kept saying, ‘Stop joking around, stop joking around!’ I keep thinking it’s borrowed and I have to give it back at some point,” she recalled.
