Estella Wilkins-Dinnigan: Meet the daughter of Richard Wilkins and designer Collette Dinnigan

Richard Wilkins shared a glimpse into his colourful family life as he wished his rarely-seen daughter Estella a happy 18th birthday. 

And while her half-brother Christian, 26, is no stranger to tabloid headlines, Estella has preferred to stay out of the public eye. 

Estella is the only daughter shared by Richard and his former lover, fashion and interior designer Collette Dinnigan.
