We had a special, SUPER secret guest on tonight's show. His name is Mike Dirnt, and you might know him as the bassist for infamous punk pioneers Green Day.
Yes. THIS Green Day:
Mike and his wife Brittney called in to the show to talk (of course) about Mr. Dirnt's most famous music project, Green Day, but also about Brittney's recent diagnosis and experience with breast cancer.
In fact, Mike's taking part this weekend's Celebrity Poker Tournament and Casino Night in Beverly Hills!
