Rosario Dawson kept her mother Isabel Celeste waiting 90 minutes at Old Homestead Steakhouse on Friday because the star was stuck on the set of Chris Rock’s movie “Finally Famous.”

Spies said Dawson’s mom was left cooling her heels while waiting for Rosario to show up for lunch.

Also at the table, keeping Isabel company, was producer Bruce Charet.

Rosario finally appeared, and a spy said, “She had a good excuse — a movie shoot that went past schedule.”
