Moments later, the 'Toxic' singer picked out a male individual from the crowd who happened to be celebrity blogger Perez Hilton. As her backup dancers grabbed Hilton onstage, he was placed in outfit of leather and chains, and Spears quickly began singing "Freakshow" while Hilton was being walked like a dog.

"@britneyspears just made me her bitch - literally! Hope @Rihanna doesn't get jealous! It was like the Circus tour opening 2.0. #PieceOfMe," he tweeted after the show.

Lucado met Britney through a mutual friend while working at law firm, and only last November (2013) she publically admitted that she was "in love" with him because he was "just a simple man. I adore him, he's really funny and he's really passionate. I love the fact that anything he's involved in he's passionate about and it's contagious."
