According to a WWE source who would have full knowledge of the situation, Bret Hart has indeed signed a short-term talent contract with World Wrestling Entertainment,
The WWE Hall of Famer signed the this past week and it will cover the period from 1/1 to 4/10, or through WrestleMania and about two weeks after the 3/28 show at the University of Phoenix Stadium in Glendale, AZ.
Hart simply told a reliable source that he wasn't going to lie about anything and thus wasn't going to comment on this story.
It was said that Hart wanted his signing to be kept quiet and his return to be a surprise, but that WWE couldn't help itself but all but announced it publicly on the first RAW after the ink was dry.
Should be very interesting to see what role The Hitman plays going into Wrestlemania.
