Lamar Odom has stayed silent this summer amid reports of drug abuse, a DUI arrest , a trip to rehab and the rumored breakup of his marriage .

But on Tuesday he took to Twitter and unloaded on one person: his dad.

Joe Odom, who has had a turbulent relationship with his son, recently spoke out about his son's troubles and blamed them on wife Khloe Kardashian, whom he calls "controlling," and her family, particularly mom Kris Jenner, whom he calls "an evil b****."

"They brought him down," Joe Odom told RadarOnline.

Don't bring all that negativity to Jenner, who's busy having a good time celebrating the release of Drake's new album with him.

Odom has been mostly silent on Twitter for nearly three months, although on July 12 he tweeted in part, "Wifey is real," a reference to Kardashian.

Odom, who played for the Los Angeles Clippers last season, is a free agent and has yet to sign with a team. NBA training camps open next week.
