Beyonce jumps off tower twice

Beyonce posted this photo of her Sky Tower jump to her Instagram account.

Beyonce prepared for her final New Zealand concert last night with a double leap from Auckland's Sky Tower.

Staff at the tourist attraction were surprised when the superstar singer showed up unannounced about 10.30am. She was surrounded by minders and enjoyed two bungy jumps.

"She got changed into the bungy clothes out the back somewhere and was taken straight up in a service elevator," one worker told the Herald on Sunday.

"It was difficult to see her when she came down because she had so many bodyguards with her.

"It was all over very quickly and bosses kept it quiet from everyone because they didn't want word getting out and risk huge crowds turning up to watch.

"She did the whole thing virtually unnoticed."

The worker added Beyonce had enjoyed the first jump so much she asked for a second, before she "disappeared as quickly as she arrived".

Staff at the SkyJump declined to comment about the star's visit.

Beyonce, 32, arrived in Auckland from Paris on Wednesday on a private jet for the New Zealand leg of her Mrs Carter Show World Tour. She was carrying her 22-month-old daughter Blue Ivy when she got off the plane at Auckland Airport. Her husband, rapper Jay-Z, was not with her for four sold-out gigs at the city's Vector Arena as he is on tour in Europe.
