Michael C. Hall is officially off the market! The Dexter star got married for the third time on Monday when he tied the knot with girlfriend Morgan Macgregor in a surprise ceremony at City Hall in NYC. Michael has been dating the LA-based writer since 2012 after he split from ex-wife and former costar Jennifer Carpenter. Michael was also previously married to Amy Spanger from 2002 to 2007. Congratulations to the happy couple!
