The grandmother to Ashlee's son Bronx, 3, and Jessica's daughter Maxwell, 6 months, looked serene and giggly as she grabbed lunch with pals.

"Papa Joe," meanwhile, hit the links one day earlier -- playing a round a golf with a group friends in Los Angeles, and sporting a close-cropped new haircut.

Confirming a divorce filing to Us Weekly last Wednesday Oct. 24, a Simpson family rep said, ?It is an amicable split and there is no third party involved.  Any other related allegations are completely false."

54-year-old Joe, longtime manager for both of his daughters, had a challenging summer leading up to the split: He was arrested in August for driving under the influence.
