'GMA’ Team Competes in Halloween Monster Mash Dubsmash in Times Square

This year's "GMA" Halloween costumes included Donald Trump and Taylor Swift.

George Stephanopoulos appeared as British singing sensation Ed Sheeran, complete with a guitar and arms full of tattoos.

“You bet,” Stephanopoulos-as-Sheeran replied when asked whether he thought his singing skills would win him the competition.

“I plan on building a wall between myself and the competition,” Spencer joked in character as Trump.

Ginger Zee smashed her way into the competition as “The Hulk,” while Amy Robach entered the dubsmash competition as pop superstar Taylor Swift.

Robach’s costume included cardboard cutouts of Swift’s “squad” of friends, including supermodel Gigi Hadid.

“I do not want to create any bad blood here,” Robach said as Swift. “I mean the haters are going to hate. I’m just going to shake, shake, shake.”

After the contestants made their grand entrances outside in Times Square, they made their way into the “GMA” studio for the monster mash dubsmash competition.

An all-star panel of judges was then announced by “Ken” and “Barbie,” who came to host the dubsmash competition still in their toy boxes.

First up at the monster mash judging table was “GMA” weekend co-anchor Dan Harris dressed as the wizardry star of book and film, “Harry Potter.”

Katy Perry was a surprise judge as well, with “GMA” weekend co-anchor Paula Faris showing up in costume as the pop singer. Faris-as-Perry was accompanied by her two sidekicks from last year’s Super Bowl, “Left Shark” and “Right Shark,” played by Rob Marciano and Ron Claiborne.

Two celebrities who know a lot about facing the wrath of a judges’ table – former “Dancing With the Stars” champions Maksim Chmerkovskiy and Rumer Willis – also joined the “GMA” monster mash dubsmash judging panel.

The panel of six judges watched and judged the monster mash dubsmash stars lip-sync and dance but ultimately it was “the Donald” dancing to “Watch Me (Whip/Nae Nae)” who took home the crown.

“Is this not a speech opportunity?” Spencer-as-Donald said when the votes were announced. “I would just like to say you’re welcome for me being here.”
