Katy Perry glimmered as she sat perched on a swing, dangling above the 2011 Grammys stage while she performed a blend of her songs in the name of love.

The "bonefide pop star," as David Ryan Harris called her, cast personal wedding footage of her and hubby Russell Brand onto a huge white sheet as she sang 'Not Like the Movies.'

"This one goes out to all of the Valentine lovers," Perry said as she led into a 'Teenage Dream' performance that had everyone -- even Nicole Kidman -- singing along.

Katy Perry is nominated for four awards at the 53rd Annual Grammys.
