You probably already know that Glee star Heather Morris came this close to being a finalist on Season 2 of So You Think You Can Dance. Although Heather was eliminated at the eleventh hour, her luck definitely turned around when she was cast as Gleek favorite, Brittany S. Pierce. Apparently, much like her airheaded character, Heather's quite the trendsetter in real life, too. Check out all of these other SYTYCD alum who have appeared on Glee:

Season 4: Katee Shean, Kherington Payne, and (Season 7 All-Star) Comfort Fedoke
This hot threesome rocked their inner bad girls when they portrayed members of New Directions rivals, Janes Addams Academy, in Season 1, Episode 11: "Hairography." Katee, Kherington, and Comfort performed Destiny's Child "Bootylicious"... hot, hot, hot!

Season 3 / Season 7 All-Star: Lauren Gottlieb
This saucy minx jumped on the Glee train before it left the station! Lauren appeared in Season 1, Episode 1: "Pilot," and then again in Season 1, Episode 3: "Acafellas."
Season 5: Janette Manrara and Jason Glover
Spicy salsa dish, Janette Manrara, and cutie-pie contemporary artist, Jason Glover, both took the Glee stage in Vocal Adrenaline's interpretation of "Bohemian Rhapsody" during Season 1, Episode 22: "Journey." Nice work!

Season 4 / Season 7 All-Star: Mark Kanemura
The contemporary cutie from Hawaii got on his hip-hop when he appeared on Season 2, Episode 2: "Britney/Brittany." Mark joined Brittany and Santana in their epic take of Britney and Madonna's "Me Against the Music," and he also performed in "I'm a Slave 4 You."

Season 4 / Season 7 All-Star: Courtney Galiano
America's sweetheart, Courtney Galiano, made two back-to-back cameos on Glee, first as a pregnant backup singer for Quinn during a rendition of James Brown's "It's a Man's, Man's, Man's World" in Season 1, Episode 21: "Funk," and then as a Vocal Adrenaline member in Season 1, Episode 22: "Journey."  

Season 5: Melissa Sandvig, Brandon Bryant, and Jonathan Platero
The memorable ballerina was a perfect choice for Season 1, Episode 17: "Bad Reputation" when Rachel belted out "Total Eclipse of the Heart," during a passionate balletic number. Intense! Meanwhile, contemporary pro Brandon Bryant appeared in "Total Eclipse...," as well as the Olivia Newton-John oldie, "Physical," along with fellow competitor, salsa dancer Jonathan Platero.

Season 6: Nathan Trasoras
Last but not least, contemporary talent Nathan Trasoras had the enviable privilege of striking a pose in Sue Sylvester's unforgettable parody of The Material Girl's classic, "Vogue," during Season 1, Episode 15: "The Power of Madonna." Sue Sylvester, dance on air!
