Mom: Britney Mentally Unsound Spears is too wacky to give deposition, parents argue By Mary Papenfuss, Newser User Posted May 16, 2011 5:24 AM CDT 5 comments Comments Singer Britney Spears arrives at a Los Angeles event over the weekend. (AP Photo/Dan Steinberg) (Newser) – Remember crazy Britney Spears? She seems to have been tootling along rather well. But apparently she's still a tad mentally incapacitated. That's what her parents are arguing in court as they battle a lawsuit from booted manager Sam Lutfi, reports KSFM. He's suing Brit's mom, Lynne, for defamation for writing in her book that he isolated the pop star from her parents and was a major negative influence. He's seeking a deposition from Britney to prove that wasn't the case. Now Britney's parents are trying to convince a judge that she's not mentally capable of giving a deposition, reports Billboard. Lutfi is demanding a shrink exam to prove it. Stay tuned.
