When does Chris Colfer think Kurt Hummel was at his most fierce? The Emmy-nominated Glee actor sat down with TVGuide.com last month to reveal his personal highlights, from the Lady Gaga heels to "Defying Gravity."

Performing Lady Gaga's "Bad Romance" in the episode "Theatricality" "Lady Gaga. 10-inch heels. Dancing. Need I say more?"

Joining Coach Sue's Cheerios in the episode, "The Power of Madonna" "Who besides Kurt would have ever thought he'd be a Cheerio? The Cheerios uniform has a certain fetish quality to it, too."

"It takes a very secure person to dance in a leotard in front of millions of people... So how did I manage to?"

Donning a Dolce & Gabbana See-Through Raincoat in the episode "Mash-up" "I wore a two-thousand dollar coat just to have it get ruined by a slushie."

"That Gucci sweater weighed seven pounds and I lost about ten after dancing in it."

"I wore that green Alexander McQueen sweater and people told me I looked like a model in it. People lie."

"It was one of the only outfits I put together myself! Lou, our costumer, was so proud."

"It was such a defining moment for Kurt, and he had the most crazy accessories. A roach-broach, for goodness sake!"
