Jenna Jameson Says Goodbye to Her Kids

Jenna Jameson is a mess ... so much so her kids are now under the sole care of their dad.

Sources close to Jenna tell TMZ ... Tito Ortiz had major concerns about Jenna's ability to care for their 4-year-old twin boys. They had a confrontation over custody recently and now we're told Tito is the primary caretaker.

In fact ... Jenna has moved out of the couple's Huntington Beach home.

As TMZ previously reported ... Jenna was arrested after her assistant claimed the former porn star beat her with a brass knuckle iPhone accessory. Jenna skated on the charge, but the assistant filed a restraining order painting Jenna as an out of control mess.

Someone should probably call Lifetime STAT.
