Ben Affleck & Jennifer Garner: Our Divorce Is A Gray Area

Ben Affleck and Jennifer Garner were back together and sharing clothes Sunday while running errands around Santa Monica while their kids were in martial arts class.

Affleck gave his wife the gray crewneck off his back ... it was chilly in L.A. that morning, or maybe she just misses his smell.

They announced their split in June after Ben was linked to their nanny, but nothing's been finalized.

All signs are pointing to a reconciliation though.
