Darren Criss watched his friend and former "Glee" co-star sing "Don't Rain on My Parade," this time not as Rachel Berry, but as Fanny Brice. 

In the hit Fox show, Michele played Berry, who was an aspiring Broadway performer. On various occasions throughout the duration the show, Michele belts out one of musical's signature songs, "Don't Rain on My Parade."  

In a truly full circle moment, a fictional story became reality when Michele took over as Fanny Brice, a role famously held by Barbra Streisand and later Beanie Feldstein and her "Glee" co-star was quick to show support.
