After School have just released a sizzling hot teaser photo for their sixth single, showing the girls doing a very different kind of dance.
The group photo shows the gorgeous girls straddling poles in tight black hot pants and leggings as they show off their curves and toned legs. Some members are even sporting sexy temporary tattoos to complete the look.
Sources say the members have trained intensively at pole-dancing for over six months in preparation for the upcoming comeback album "First Love" which is due for release on June 13.
"Some of the acrobatics they can do is incredible," an insider tells IdolWow!. "People will be gobsmacked when they see how much work has gone in to this one single. It's amazing."
It's not the first time After School have gone to great lengths to learn complicated choreography for their performances. They have previously learned tap dancing and drumming.
"We are a very dedicated group," Nana has said. "We put our all into every performance."
