Jenna Dewan-Tatum and her female co-stars on new TV drama The Playboy Club were forced to undergo a full day of "bunny training" to perfect their poses as the iconic waitresses.

The Step Up star features alongside fellow 'Bunnies' Amber Heard and Naturi Naughton in the new show, about publishing mogul Hugh Hefner's first Playboy Club in Chicago, Illinois.

The actresses were given special lessons on how to behave from former Playboy Bunny Pat Lacey, but Dewan-Tatum admits the one-day course was a little more intense than she had ever expected.

She tells PR.com, "We had Pat Lacey, who is an ex-Playboy Bunny and still works with Hef, come in, and we had a day of bunny training.

"You get that memo from your agent and you're like, 'OK. Maybe it's just to talk research about what it was like being a bunny.' We got there and it was strict! There's a certain way the drinks are placed on the tray. There's a certain way you have to place them on the table.

"The bunny dip, the bunny stance, the bunny perch... there were so many technical things to being a bunny. I left that day having a whole new found respect for the Playboy Bunnies and what they did for 12 hours a day."
