Michele took to Instagram, posting a pic with Tobin and her fiancé, Zach Martin, writing, “Celebrating this happy couple tonight! @itsbeccatobin & @z.mart love you both! Thank you @figandolive.”
For the event, the bride-to-be wore a white jumpsuit with sheer lace cutouts while Michele rocked a black dress with a plunging neckline.
Tobin announced her engagement back in May on her LadyGang podcast, saying, “I got engaged! Every single person thought I was kidding. I thought he was kidding when he had the ring in front of my face."
Martin seems smitten with his future wife, posting a pic of her last week with the caption, “My favorite person.”
Tobin joined the cast of Glee in 2012 as the often-blunt Cheerio, Kitty Wilde. She and Michele got closer in 2014, when Tobin’s then-boyfriend, Matt Bendik, was found dead in his hotel room just days before the one-year anniversary of Cory Monteith’s eerily similar passing.
