Ann Romney faces 'cooking emergency' on morning TV

It was the prospective first lady's first foray behind the camera for "GMA." Romney helped host for an hour of the morning show, filling in for Robin Roberts, a regular co-host who is on medical leave.

According to a tweet from her press secretary, Sarah Haley, Romney wore a bracelet in Roberts's honor during the appearance. The bracelet read, "Light, love, power, presence." 

Romney was introduced in the "GMA" kitchen at the top of the second hour of the show, where she was making her famous Welsh cakes live. She was speaking off camera when the regular co-hosts began to introduce her.

"I've got a cooking emergency," she laughed. "The grill's too hot."

She was back in the kitchen later with Stanley Tucci, demonstrating a pasta recipe from his new "Tucci Cookbook."

Romney told Tucci she "loved" his 2009 movie "Julie and Julia," where he played the husband of famous chef Julia Child.

"They burned my Welsh cakes, too," she told Tucci when his butter burned despite his warning that it was too hot.

"This show's a disaster, I tell you," Tucci joked, shortly before the butter started smoking. The "GMA" crew joked that the Secret Service were getting tense and apologized for almost blowing up the wife of the GOP presidential nominee.

"My plane almost goes down, now I'm going to catch on fire?" Romney joked. A plane carrying Romney and her staff was forced to make an emergency landing last month when smoke filled the cabin.

During the show, Romney also helped interview two couples voted off Tuesday night's reality dancing competition "Dancing With the Stars." She asked two questions of former "98 Degrees" singer Drew Lachey.

Romney seemed somewhat uncomfortable with the format of the show and missed her cues more than once. But when the hosts moved outside to Times Square, she acknowledged that she felt right at home next to a horse belonging to Paralympian Rebecca Hart.

Romney actually knew Hart and her horse, Lord Ludger, having presented Hart with the top prize for the Para-Equestrian Dressage National Championship earlier this year.

Romney is an advocate for therapeutic riding and often speaks to its benefits for her multiple sclerosis.

"It's so extraordinary what horses do for us. For me it's balance, it's love, it's joy," she said, before kissing Lord Ludger on the nose. "Horses are a gift from God, is the way I look at it, and they're a partner in our life's journey."
