X17 XCLUSIVE - Source Tells X17 Britney Exploring Possibility Of A Restraining Order Against Her Mom!

A source close to Britney has just given X17, exclusively, some shocking news - Britney's visit to her attorney's office yesterday may have been part of Spears' research into filing a restraining order against her own mother, to keep Grandma away from Jayden and Sean!

Britney and Lynne's relationship soured when Brit was forced into rehab by her family and management (according to Brit herself) and when it appeared that Lynne was taking Kevin's side in the custody battle involving her own daughter and her daughter's estranged husband.

Then reports had the mother and daughter reconciling last month and we did catch Brit's mom and her daughter's Bel Air home, but Britney was mum on mom the following day when we asked if she was happy to see her mom again.

We haven't seen the two together since then and now our source is telling us there are some very deep problems between the two. Apparently Britney feels the situation is serious enough to file a restraining order against her own mother to keep her mom away from her two sons, according to our source.

We'll do our best to gather more information on this developing story and bring it to you as soon as we can!
