She may or may not be voicing Knut the polar bear in a new movie about the ursine specimen, but Suri Cruise looks destined to be an entertainer.

Not only is the 21-month-old a fan of the Spice Girls, but according to mother Katie Holmes, she has also become a fan of American Idol.

Holmes â€" who is getting panned by critics for her comedy Mad Money â€" told Ryan Seacrest about Suri's American Idol passion on his radio show.

When Seacrest said he could probably hook the Cruise clan up with some tickets, the soft-spoken Holmes said, "I would be very grateful."

Holmes did not comment on whether Suri believes current Idol hopefuls Kady Malloy, Kristy Lee Cook and Carly Hennessy are all ringers.

Maybe Suri Cruise will audition for American Idol herself one day.

For now, Katie has her hands full with baby Suri, who is "is growing fast and talking more and more. I am constantly surprised."

She probably felt the same way about that Tom Cruise Scientology video.
