Britney Spears has hand-picked Sydney dancer Shannon Holtzapffel to be her dance partner in an upcoming video clip.

The 23-year-old finished filming the clip for Spears' song, Mannequin, in Los Angeles this month and spilled the beans to Insider on his return home to Australia.

"It's documentary style of us all in a rehearsal studio with her (Spears),'' said Holtzapffel, who dates Channel V presenter Renee Bargh.

"I get very close to her. There's one part where we rest heads together and I'm resting on her neck before she pushes me away.
