On Friday, Lindsay Lohan must return to court to inform the judge whether she wants to accept a plea or take her felony theft case to trial. Despite claiming her innocence from the beginning, sources say Lindsay's brain made a wave. TMZ reports:

Lindsay Lohan's confidence is starting to wane -- sources close to LiLo tell us she is finally getting it through her head she can't avoid jail and is now "seriously considering" taking a plea deal. As TMZ first reported, Judge Keith Schwartz offered LiLo and her attorney Shawn Holley a deal that includes three months in jail ... which get whittled down to 19 days because of jail overcrowding. Lindsay has been adamant for weeks ... she would never take a plea deal because she feels she did nothing wrong. Sources close to Lindsay tell us she still maintains her innocence ... but reality is starting to sink in and Lindsay is beginning to understand the risks of going forward with a trial.

19 days in jail or the strong possibility of spending a year in state prison? If I were Lindsay, I'd really have to go back and forth on that one. Be out before bikini season or updating her NFL fantasy team while getting fisted by a chick with a teardrop tat and no reason to live? Man, that's a tough one. I may just have to retire to my study to ponder this some more.
