TORONTO, Ont. – Sixteen-thousand fans crammed into the Air Canada Centre Sunday night to be part of Lady Gaga’s “Monster Ball” concert.

It was the first of two sold-out shows. The second one will be held Monday night.

This was glam at its best as fans came dressed up in some wild outfits such as dominatrix leather.

The two-hour concert had it all: dancers, special effects, video images, outrageous and over-the-edge costumes and of course, great music.

Fans were also treated with an appearance of Elton John who surprised everyone by showing up to watch the concert.

Gaga turned the show into a celebration of life, and fans loved what they saw and heard.

“That was the best concert I’ve ever been to in my life,” one fan said. “She’s just amazing,” another said.

“This show was epic, unbelievable, I am speechless,” one woman said. “That was awesome, we enjoyed every minute of it,” another added.

Blair gave it four out of five sparkles and said so far, this was the best concert of 2010, adding that people got their money’s worth.

He also said Gaga reminds him of a combination of Elton John, David Bowie, Madonna and Cher all rolled up into one.
