John and Scarlett Play Games at Grammys

John Mayer and Scarlett Johansson didn't bring dates to the Grammys, but that didn't stop E!'s Ryan Seacrest and Giuliana DePandi from jumping on the "are-they-or-aren't-they?" train when they arrived for their carpetside chats.

"You're like the Anderson Cooper of E!," 29-year-old Mayer joked as Seacrest pulled him aside for an interview under the watchful eye of his super-powered publicist, Ken Sunshine.

Meanwhile, Johansson acted put off by even the idea anyone would think she and Justin Timberlake were an item -- even though the duo have been spending a lot of quality time together and even hung out in L.A. Friday night at T-Lake's concert.

"We did a music video together and we have a lot of friends in common," the 23-year-old actress said before denying the romance. "The last thing I want to think about is what people think about my personal life."
