Grimshaw explained to Heat magazine, "He was on the phone. I was like, 'Hi, Zac Efron'. He gave me a dirty look... but then suddenly he looked at me and said, 'Wait. Are you Grimmy? I listen every day. I'm, like, obsessed with you!'"
Nick continued, "And I said, 'I'm, like, obsessed with you!' It was so weird! He was going out with Vanessa Hudgens at the time and said, 'Wait 'til I tell V. She's gonna freak!'"
