Mel Gibson -- Out for Azita Ghanizada's Birthday

Mel Gibson continued his platonic relationship with actress Azita Ghanizada, showing up at her birthday party in Los Angeles  this week.

As TMZ first reported, the two had dinner together a few weeks back ... but her people say it was just a business affair. Mel's rep wouldn't confirm or deny whether it was strictly business.
