*A lawyer for LeBron James sent a cease and desist email to a sports blog demanding they take down a story claiming the NBA star’s mother is carrying on a sexual relationship with Cleveland Cavaliers teammate Delonte West.

TMZ obtained a copy of the email sent to terezowens.com, which reported Friday that LeBron’s mother Gloria was allegedly sleeping with Delonte. In the email, Frederick Nance — attorney for LeBron and Gloria — says the report is “categorically false and per se defamatory.” Nance adds, “No thinking person could possibly believe such rubbish.”

The report — which spread like wildfire on the Internet, also suggested that the Cavaliers’ playoff loss to the Boston Celtics was due to LeBron finding out about the affair before game 4. His team went on to lose games 4, 5, and 6.

Terezowens tells TMZ they stand by their source, and they’re consulting with their lawyers. : “We think it’s a little fishy that they waited almost four days to fire this off.” They say The story is still up on their site … for now.
