According to sources, Jon Cryer’s ex-wife may have threatened the actor on the set of “Two And A Half Men.”

Imagine that, violence and drama that doesn’t involve Charlie Sheen.

TMZ reports:

Security has flooded the set of “Two and a Half Men” after a threat was made against Jon Cryer.

Sources connected with the show tell us the threat was “significant.” We’re also told it involves the turbulent divorce with Jon’s ex-wife.

Sources tell us the taping will now go on, but because of security concerns, there will be no audience tonight.

Trigger’s mouthpiece said, “There’s no reason in the world why Sarah would do anything like that.”
