When Nicole Murphy suspected Michael Strahan was cheating on her, she wanted to catch him in the act.

In January, the “Hollywood Exes” fixture set out to find Strahan at the Regent Beverly Wilshire, where he was allegedly spending the night with another woman, TMZ reports.

Murphy, 46, located the room just before midnight and flew into a rage in the hallway. She began banging on the door and yelling out Michael’s name, saying, “I know you’re in there with some bitch.”

“It’s Michael from ‘Kelly and Michael’ in there,” she yelled.

The chaotic scene lasted roughly 20 minutes before Murphy was escorted off the property. (It’s unknown if Strahan, 42, was actually in the room, as no one ever came to the door.)

The pair announced the end of their five-year-engagement Friday, one day before Strahan was inducted into the Pro Football Hall of Fame.

They blamed the breakup on distance, not infidelity. But despite reports of the “Live with Kelly and Michael” co-host cheating, TMZ obtained pictures of Murphy on a secret Puerto Rican vacation with NBA player Jim Jackson in early July.

Page Six reported on Monday the pair actually parted ways over prenup drama.

“Nicole was unwilling to sign a prenup, even though Michael has consistently been very generous to her,” said a source.
