Conan O'Brien was Invited to Join David Letterman and Jay Leno's Super Bowl Ad

The Super Bowl ad featuring late night rivals David Letterman and Jay Leno, along with Oprah Winfrey, could have included Conan O'Brien, who was invited to join the commercial.

Rob Burnett, executive producer of David Letterman's Late Show, said he approached Team Coco about Conan appearing in the promo.

"There was an initial thought of having Dave, Jay and Conan together in the spot," Burnett told TheWrap. "I did call Jeff Ross (Conan's producer) to talk about it."

But the call came in the midst of the Tonight Show fiasco so nothing ever came of the idea.

"It wasn't as if they even said no," Burnett said. "I just think they weren't in a position to consider it all."

Meanwhile, the late night hosts referenced their 15-second spot on their shows last night, taking typically different tacks.

"As you know, I watched the game with Oprah and Letterman," Jay said in his Jay Leno Show monologue last night.

"We all watched together. Letterman and I hadn't seen each other in over 18 years. We lost touch. He found me on Facebook. He made a friend request, I accepted, and we hooked up and watched the game."
