Erin Andrews has been a reporter for ESPN since 2004.

"I would introduce her to my sister, because she's way better, way cuter," Andrews said. "But could I do one song in the concert? One guest appearance?"

Ah yes, her sister. That would be former Florida State Seminole Kendra, a dancer who has appeared in a Cheri Dennis video and who recently landed a prominent role in Step Up 3, which is due out in 2010. She flew to New York for the audition on one of Erin's frequent flier freebie flights, was called back to read for a part, and is now there for a four-month shoot.

Waiting to hear if she got the part, Erin said, "was worse than waiting for a guy to call." The night before her final audition, Kendra met Erin at Citi Field, and received advice on dealing with the pressure from Orel Hershiser, Steve Phillips and Dan Shulman. And after she made a few public appearances and saw her own pictures hit the Internet, Kendra told Erin about some anonymous comments; for example, that she had bigger legs than her sister.

"I was like, 'Oh, no no no, read all this crap they say about my nose, my voice, the way I dress...." Erin told Kendra. "It's so mean, though," the younger sister pointed out. "Ya think?" replied Erin.

Still, she said she's extremely excited and proud about her only sibling's career, and she pointed out that Kendra now has to deal with paparazzi as well. So Andrews was asked if her little sister could one day equal her fame.

"She can have it," Andrews said.
