Baldwin films with his mother, Carol.
Customers at the Fairmount Wegmans got a celebrity sighting along with their groceries this afternoon.
Alec Baldwin and his mother, Carol, were in the store filming a holiday-themed commercial, employees and shoppers reported.
The famous family put the supermarket chain on the map earlier this year, when Alec Baldwin joked on CBS' "Late Show With David Letterman" that his mother would never consider trading her home in Camillus for the West Coast, where her two sons live.
He said her reaction to the idea of moving was an incredulous, "And leave Wegmans?"
Store officials said that Alec Baldwin was polite, friendly and "looked exactly the same as he does on television."
