Michael Strahan was allegedly shocked when Nicole Murphy, his longtime girlfriend, announced their split. First it was claimed the former NFL star's busy schedule was to blame, but new reports suggest unfaithfulness and prenup arguments drove the couple to call of their engagement.

The couple started dating in 2007, but allegedly went on and off when the relationship became bi-coastal. TMZ says Murphy did not want to wait another second before ending things when she learned of another woman in Strahan's life, which was coincidentally around the time of his induction into the Pro Football Hall of Fame.

Murphy speculated at the beginning of July her long-time boyfriend was cheating, though the site did not confirm how she figured out it was true.
