A VERY BRITNEY INTERVENTION!

We are now hearing that Britney's breakdown last night was a direct result from the staged intervention that her family and friends conducted.

Among the people at Britney's home, some not mentioned earlier, were her mother Lynne, her dad, Jamie, cousin Alli, as well as Manager Sam Lutfi and on-again/off-again Adnan Ghalib!

We hear Sam took Britney for a ride to fill her in on some of the details for fear that his help in the intervention would cost him his inside slot with Spears. Britney was furious with Sam for joining forces with her parents. Britney most likely brought home the two photags to have some people in her corner or support. She didn't want to feel ganged up on.

However, after Britney finally returned home, the intervention continued as planned, they know that Britney has bipolar disorder and she needs to get help for her problems.
