GUEST STAR 4 U
Oops, Will & Grace
is doing it again — stunt casting, that is. As first hinted in the new issue of TV Guide magazine, producers have snagged Britney Spears
for a guest shot. Here are the deets: In the April 13 episode, when a Christian TV network takes over "Jack Talk," Spears is brought on as Jack's new religious cohost, even adding her own touches like a cooking segment called "Cruci-fixin's." This is also good news for Spears' husband, Kevin Federline
: He is more than welcome to drive her to the NBC studio.
