Sorry Charlie, I'm BUSY
Lisa tells us, "I am personally thrilled to death that they chose Charlie and I'm glad he's desperate enough to have accepted the challenge. I mean, come on -- the guy was replaced by Ashton Kutcher. I guess he now knows how Bruce Willis felt!"
But she adds, "Sadly, I'm actually booked to do a show that night already, but if there's any way I can get out of it, all I can say is, "Charlie, here I come!'"
The show is scheduled to tape September 10 in L.A.
Lisa ... make it happen.
