Dame Helen Mirren is a doctor after picking up an honorary degree from the University of Southern California on Friday.
The 71-year-old donned academic cap and gown for the traditional 'hooding' ceremony in Los Angeles, which funnyman Will Ferrell co-hosted with a comical commencement speech.
The Old School star, who graduated from USC in 1990 with a Bachelor's degree in Sports Information, poked fun at the Oscar winner, joking he still loses out on roles to the British actress.
"The most painful one was losing the role of Queen Elizabeth in The Queen," he quipped. "Apparently, it came down to myself and Helen Mirren. The rest is history."
Ferrell, 49, also serenaded Mirren, university staff and the graduating students with his rendition of Whitney Houston's I Will Always Love You.
