Kate Hudson's biological father has gone public with the fact the actress has a sister, who is two years younger than her son Ryder. Musician Bill Hudson has been estranged from his famous daughter for years and he now reveals the Fool's Gold star has never met his three-year-old daughter Lalania - her half-sister.

Hudson claims the actress cut off all contact with him after he first told her that she had a baby sister, shortly after Lalania was born in 2006, and now he's desperate for his daughter with Goldie Hawn to get in touch.

The Hudson Brothers star has posed for pictures with his youngest daughter and poured his heart out in the new issue of Life & Style magazine.

He says, "Katie, I love you with all my heart, and I beg you to come home and meet your baby sister. There's only a two-year difference between Ryder and Lalania, and it saddens me that they haven't once played together."
