After the wild night at Britney Spears' place on Monday, her mother Lynne Spears headed for Brit's pad for an intervention. This should have happened A LONG TIME AGO!

This morning Britney's mother was joined by her husband Jamie Spears as they launched an attack on Spears' friend turned 'manager' Sam Lutfi. Britney's parents branded Lutfi as “poison”.

Now that Britney's parents are back on the scene, Sam called up TMZ to give his side of the story. According to Lutfi, the Spears family “barged in" rather than intervened in Brit-Brit's troubled life. During the call, Sam made it very clear that Britney was by his side.

“They have an agenda. Their agenda is jealously because they don’t fit in. I do. They see her [Britney] three times a year.”

TMZ says the Spears family is planning an intervention, and they are leaving Lutfi out on purpose.

Lutfi also says he didn't make Britney buy a new Mercedes that was delivered to her home Tuesday night.

“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.”

It sounds like Sam Lutfi is to Britney Spears as Howard K. Stern was to Anna Nicole Smith. We all know what happened to Anna Nicole!
