Sam Lutfi took the stand this morning in his defamation case against X Factor judge Britney Spears and her family and made claims that Brit's dad, Jamie, threatened his life back in 2007.

Spears' former manager says he has a text from Jamie Spears that reads, "If and when I met u one thing is going to happen I am going to jail and u r going to the hospital."

Lutfi went on to tell the judge that Jamie attacked him at Britney's house and punched him in the solar plexus.

In 2008, Lutfi had told X17online about these threats. We caught up with Jamie Spears that year and asked him about Lutfi's claims. Check out our archive video.
