Jane was all smiles as she struck a pose at the ‘La Tete Haute’ premiere in a strapless gown complete with a tasteful split.
We can’t quite believe that Jane is 62 to be honest. Let this be a lesson in growing older glamorously.
The premiere was the first of many that will take place in the French town this week, and the festival’s official opening ceremony also took place last night (Wednesday 14 May).
Jane was joined on the red carpet by a whole host of Hollywood A-listers, including Julianne Moore, Naomi Watts and Natalie Portman.
