(Yahoo!) - It looks like Beyoncé has found a new favorite dance.

Following the "Single Ladies (Put A Ring On It)" singer's concert Saturday at New Zealand's Vector Arena, the country's All Blacks rugby team surprised her with their traditional Haka dance.

The 30-second routine filled with two-dozen men grunting, flexing and chanting turned into a faceoff as Beyoncé did her best to keep up. She growled, cheered and even stuck out her tongue to show her gratitude.

"She didn't know about it and was completely surprised when she ran off stage and was suddenly welcomed by the Haka," a rep for Sony, Beyoncé's label, told The New Zealand Herald. "The energy was so intense, she started doing the Haka back."

According to a video posted on Beyoncé's YouTube channel Thursday, the All Blacks perform the ritual before international rugby matches to "intimidate the opponent," though it is also used to "honor a distinguished guest."

The All Blacks have been performing variations of the pre-game custom since 1888. It is a traditional dance of Maori, indigenous Polynesian people of New Zealand.
