Adriana Lima and Alessandra Ambrosio dazzle at Victoria’s Secret show

It was a night of glamour, rhinestones and well-toned flesh at the 2014 Victoria’s Secret fashion show on Tuesday in London, and leading the way were Brazilian top models Adriana Lima and Alessandra Ambrosio.

The duo sashayed their way down the catwalk wearing lingerie paired with sparkly, over-the-top costumes like giant butterfly wings, full feather skirts and gold, knee-high, high-heel boots.

But the highlight of the annual spectacle were the Victoria’s Secret Fantasy Bras – this year's editions were encrusted with 16,000 rubies, diamonds and sapphires strung together with 18-karat gold and worth $2 million each.

Lima, 33, wore the blue and silver version, while Ambrosio 33, had the pleasure of wearing the red bra. They also donned large, flowing capes that matched the color of their underwear.

It may end up being a bittersweet show for the two supermodels, who have represented the lingerie company for years. Unnamed sources told the New York Post's Page Six last month that this would be the last trip down the runway for the duo. The report hasn't been confirmed.

Singer Ed Sheeran performed while the ladies as they stepped out in the coveted bras.

Asked whether he was nervous about singing so close to scantily-clad women, Sheeran joked, "That's how I usually perform."

"It's one of the only times I've ever played when the attention isn't on the musician, so it's an odd thing." he admitted.

The Victoria’s Secret Fantasy Bras were first unveiled in early November when the lingerie company announced that this year there would be not one Fantasy Bra, but two.

“It’s like a highlight, really, of the show, the Fantasy Bra, and every year the models, we always get nervous to see who is going to get to wear the bra,” Lima said last month. “This year it’s really exciting because it’s the first time that we’re going to have two fantasy bras on the fashion show. I’m honored to be here with Alessandra, doing the show, walking the runway together. I cannot wait.”

Unlike most mainstream fashion shows, models walking for the lingerie label are told to have fun and flirt with the audience. They also got to wink, dance and laugh onstage with Taylor Swift, who appeared in a glamorous pink and black lace outfit. The singer later changed into racy black lingerie and a matching lace cape.

Ariana Grande also performed at the show as the models strutted around her.

The show will air in the U.S. on CBS on Dec. 9.
