SAM LUFTI FIRES BACK!

Sam Lufti is pissed at Britney's parents! He claims on Monday night just "barged in."

"They have an agenda. Their agenda is jealously because they don't fit in. I do. They see her three times a year."

During the phone call to TMZ.com he also claimed he did not force Britney to buy a car, asking Brit, "Did I force you to buy a car." In a heavy southern accent she responded, "No." He continued, "Do I ever bug you." She replied, "We argue."

Weird.Shady.Sad.
