has some advice for the unlucky gal who replaces her as Regis Philbin's co-host on Live! With Regis and Kathie Lee
. "She's going to have a little honeymoon, and then they're going to turn on her every bit as much," Gifford said Tuesday during an appearance on Fox News Channel.

And if she's successful with Regis... she's going to have to know that fine line between how much to kick his rear end and how much to kiss it."
