When the Michelle McGee story broke last week and Sandra Bullock walked out on Jesse James, who didn’t see this one coming?

from www.tmz.com – We’ve learned Janine has filed legal papers in their custody case involving six-year-old daughter Sunny. Currently Jesse has full custody of Sunny. Janine lives in a halfway house, after being locked up for tax evasion.

We’re told until this week Janine knew she didn’t stand a chance of gaining even partial custody from Jesse. She felt Sandra Bullock was such a stabilizing family influence, a judge would shut her down.

But Janine now believes Sandra will divorce Jesse and she feels she has a shot at getting some custodial rights.

Her court date is set for June 14.
