Aburrido como bailar con la hermana ?

Tango sobre hielo... con la hermana.

Sinead y John Kerr, en el European Figure Skating Championship

Four of the ice-dancing pairs competing in Vancouver are siblings—and this year, there's a compulsory tango routine.

When Alexandra Zaretsky takes to the ice in Olympic ice-dancing competition Friday, she'll look deep into her partner's eyes as they skate the "Tango Romantica."

But not too deep. That's because her partner is her brother, 26-year-old Roman Zaretsky. "We try to find ways to kind of look through—or look a little up, or a little sideways," says Ms. Zaretsky. "Hey, you gotta act."
