As well as pulling a few style surprises out of the bag, the 67-year old starlet smooched hubby Taylor Hackford and struck a series of poses for snappers on the red carpet.
Setting flashbulbs alight, the actress put her fashion foot forward in a sweeping, emerald Elie Saab frock, teamed with a shiny gold clutch and statement coral jewels.
But it was her heels we were really interested in.
On her feet Ms. Mirren wore what we can only describe as stripper shoes - and proudly showed them off with a sneaky smile to cameras.
Earlier this month, Helen Mirren addressed rumours she could be set to replace Matt Smith as the first ever female Doctor Who.
While excitement reached fever pitch among fans, British starlet quickly ruled herself out of the running.
'I do think it’s well over-time to have a female Doctor Who,' she said. 'I think a gay, black female Doctor Who would be the best of all,' she told ITV's Daybreak show.
Confirming she won't be taking on the part, she added: ‘I’m not going to be the first female Doctor Who, no, no, no, absolutely not, I absolutely wouldn’t contemplate that.'
Well that told us, then!
