Reps for both actors declined to comment on the couple's personal lives.
Jenner, 20, and Benoist, 24, only recently acknowledged they were dating during a Twitter chat with ET Canada. When a fan asked Jenner if he was dating Benoist, The Glee Project winner responded: "Yes I am!!!"
Benoist plays Marley Rose, the new addition to New Directions who filled the void left by Lea Michele's Rachel when she graduated. Jenner beat out 13 contestants on The Glee Project to earn his role as Ryder Lynn.
