And here we were, years later as friends and colleagues, enjoying the most glorious night ever!’

‘We’d spent weeks prepping, working, sitting next to each other every morning in makeup chairs, preparing for the day together as mother and son. I am honored that we enjoyed that full circle experience,’ penned the actress.
