They're all in town for Joel Osteen's Sunday Service at the Lakewood Church. TMZ broke the story ... Kanye will appear at Osteen's 11 AM service, walk up to the pulpit and have a half-hour conversation with Joel about his freshly formed commitment to God.
There will be an evening service as well. Kanye is bringing his choir -- we're told around 120 strong -- and the 45,000 seat venue is expected to be overflowing with fans. Tickets are being distributed through Ticketmaster for free, but they're already having problems with scalpers.
Check out TMZ tomorrow, and we'll show you the service.
