Salling, 28, didn't deny that it happened; instead, he joked about it.
He says he wishes Rivera had thrown "some mushrooms" at his car.
When Seacrest asked him flat-out if it happened, he teased, "They should throw a cheeseburger at my car. I'd appreciate that!"
The new Us Weekly reports that though he and Rivera, 23, were never an exclusive couple, his dates with other women this summer caused an infuriated Rivera to egg and key his pricey car.
Rivera “went crazy when she read about other girls,” a source tells Us Weekly. “When Naya found out, she and some pals trashed his Lexus."
