Hudson90210.jpgKate Hudson just might be making a special guest appearance on an upcoming episode of 90210 - or she might not. Kinda depends on who you believe.

According to InTouch Weekly, Hudson has agreed to do the show as a favor to her pal Sarah Foster, who plays the older sister of AnnaLynne McCord's character, Naomi.

"Kate’s a movie star and doesn’t usually do TV shows," an insider tells In Touch. “But she and Sara are pals and have always wanted to work together, so Kate said she’d do it."

Best quote ever, right?

Anyway, Kate's peeps totally deny the story -maybe movie stars really don't do TV!
