Jose Canseco saw the news of Alex Rodriguez and Jennifer Lopez getting engaged and wanted to be the bearer of bad news.

Canseco claims his now ex-wife Jessica had an affair with Rodriguez and continues while with Lopez. He then later applogizes to Lopez and calls Rodriguez a “piece of sh**.”

Jessica says she hasn’t seen Rodriguez in five years and is actually friends with the couple. Canseco refuses to let it end there and threatened a polygraph test.

“Do not turn away or hide from.a polygraph,” tweeted Canseco.

In his 2008 book “Vindicated “, Canseco speaks about the affair while he was still married to Jessica.
