When it came to asking Aaron Hernandez about personal friendships, his fiancée never pried.

The imprisoned former NFL star's fiancée, Shayanna Jenkins-Hernandez, took the witness stand Thursday in court and testified that she never pressed Hernandez about his friend Alexander Bradley being shot, explaining that she'd "learned to keep my mouth shut," as reported by the Daily Mail.

This was part of her testimony today during Hernandez's double-murder trial for the July 2012 homicides of Daniel de Abreu and Safiro Furtado.

Hernandez allegedly shot Bradley in the face in February 2013 over paranoia that his then-friend was going to rat him out about the double-murder.

Jenkins-Hernandez insisted that she never asked Hernandez about Bradley.

"I learned to keep my mouth shut in certain situations," she said, as reported by the Daily Mail. "I played my role. Meaning I cleaned and I did everything else. There was no reason for me to ask any questions."

She added, "I pick and choose my battles," explaining that "there are some things worth arguing about. I didn't see that as one of them."

Jenkins-Hernandez, who never married Hernandez but legally changed her last name, also said that "it was a sad situation but why would I press on that?"

Last week, Hernandez's lawyer, Jose Baez, questioned Bradley about a deleted text message that he sent to his attorney, Robert Pickering, in 2013, saying, "Now you sure once I withdraw this lawsuit I won't be held on perjury after I tell the truth about me not recalling anything about who shot me?"

But when questioned about why he deleted the text, Bradley said, "For the fourth time, I don’t recall what calls or messages I have or have not deleted."

Bradley added, "I was trying to figure out how I could testify without getting [Hernandez] criminally [charged]. I would essentially perjure myself if I file in a civil matter that Mr. Hernandez shot me and then I go to the grand jury and say, 'I don’t know who shot me.'"

Bradley was referencing his civil lawsuit, which was settled last year for an undisclosed amount.

Hernandez's defense contends that Bradley was the gunman who shot and killed de Abreu and Furtado during a drug deal gone bad. Meanwhile, Bradley claims that Hernandez shot and killed the two men after de Abreu bumped into the football player in a Boston nightclub, spilling a drink on him.

Earlier this week, prosecutors said that a heated argument between Hernandez and Bradley about the double-homicide led to Hernandez shooting Bradley.

Hernandez is already serving life in prison without the possibility of parole after being found guilty two years ago of the 2013 first-degree murder of Odin Lloyd.
