Matthew and girlfriend Renee attended the Geffen Playhouse’s Annual “Backstage At The Geffen” Gala last night (June 4). All the pictures here!—–Edit: Lapsing into her TV persona, Sue Sylvester, Lynch introduced Morrison as “the man I love to torment,” saying she’d been “carrying him” on GLEE “for what seems like 100 years.”“You see who’s hosting the Geffen Gala,” she said. As a proper and polite host, however, she recited his credits, including his starring musical theater roles in “Hairspray,” “Light in the Piazza” and “South Pacific,” before adding, “I will never be friends with his hair.”Morrison then belted out “Come Rain or Come Shine” and “Lady is a Tramp”, before his girlfriend Renee Puente further lit up the theater by joining him onstage to dance. They had performed the same number the night before for the Obamas in DC.And even more fun was when Matthew was seen talking to Jane Lynch at the dinner about how much fun his Halloween party was last year, and that he’s already started planning the next one this fall. Which gets us thinking, what kind of Halloween costumes should they bust out for the big party this year? At least they have plenty of time to figure it all out!Sources: 1 – 2 – 3.
