The world-famous Rockettes are supposed to look alike, but fans this Christmas might do a double take - and then a triple-take.

Three long-legged, athletic sisters - including identical twins - are in the Radio City Christmas Spectacular lineup. Landing a job among this high-kicking chorus line is very special. Can three come from the same family?

Meet Kristin, Lisa and Alison Jantzie, celebrating their fourth year as Rockettes together. The brown-haired, blue-eyed sisters are from the rural community of Lacombe, in Canada's western Alberta province.

"It's kind of wonderful to be onstage with your family," said Alison, dance captain in the recent Broadway show "Gigi," with Vanessa Hudgens. "We've kind of made this a tradition for ours, obviously."

Kristin, in her 11th Christmas show, was the first to be a Rockette. She and her twin, Lisa, technically the oldest by a few minutes, got their first professional jobs at age 18 at the Tokyo Disney Resort.

Kristin later auditioned for a touring production of the Rockettes in Los Angeles and got the job after showing her skills at tap, jazz and precision dance. Both of her sisters went to see her when the show went to Detroit in 2005.

Lisa looked at the stage and, well, saw herself: "When you see somebody you know doing something, it kind of does open your eyes to the possibility."

Kristin's sisters eventually joined her at Radio City Music Hall, but took their own routes. Lisa, who gravitates toward ballet, worked at the National Ballet of Canada and Alberta Ballet. She's in her sixth Rockette show, and she and Kristin were in the recent spring Rockettes show.

Alison, the youngest, loves musical theater and studied at the Randolph Academy in Toronto. She acted in regional productions of "Cats," ''High School Musical" and "Mary Poppins." She's in her fourth Radio City show.

The sisters are split into two rotating, 40-person casts - with Kristin and Alison in one and Lisa in the other.

Some weeks they'll perform 17 shows a week, and having some sibling love is both helpful and motivating.

"It's always fun to look across the rehearsal hall and catch their eye and be like, 'OK, here we go, 5-6-7-8. Let's begin!"' said Alison.
