In a tribute, Bosworth’s stepdaughter Jasper (from Michael’s first marriage to make-up artist Jo Strettell) thanked her for being her ‘mentor and guardian for the past 11 years.’

‘Happy Birthday Madre!’ the 23-year-old actress gushed. ‘From the moment we met you’ve been the warmest most loving women and have been there for me every step of the way. You are not only a mother figure to me but a best friend, I love you so much.’

The Los Angeles native and Polish’s love – which she called ‘life’s greatest achievement’ – originally began in mid-2011 when he directed her in his dismally-reviewed film Big Sur. 

Kate and the Force of Nature filmmaker are reportedly shopping around their 10-episode modern western drama Bring on the Dancing Horses, which they shot in Montana where they wed.
