Actor Rob Lowe has revealed that Hollywood star and “competitive” Tom Cruise, with whom he starred in the 1983 crime thriller The Outsiders, knocked him out during an impromptu session of sparring, a form of training common to many combat sports including kickboxing. “The next I knew, I woke up – I was coming to, on the floor,” Lowe said. The revelation came as Lowe was asked on a recent episode of the Rich Eisen Show for a memory working alongside the Mission: Impossible star, reports mirror.co.uk. “He’s so competitive that we used to box in the hallway of the hotel we were staying at during Outsiders So much testosterone,” said Lowe.
