Miranda Kerr's family haven't seen her in a year

Miranda Kerr's family, who have not seen the supermodel or her son Flynn in over a year, have made an emotional public plea for her to come home.

In a "love letter" from Kerr's mother Therese, father John, brother Matthew and nanna Ann, the clan have used an episode of an Australian docudrama series, Family Confidential, to expose cracks in their relationship with the catwalk star, the New York Post reported.

Therese was sacked by her daughter in her role as the managing director of Miranda's Kora skincare range last year.

Miranda's father John and nanna Ann both despair at the growing distance between the fashionista and their grandchild Flynn, now 3, who they fear is "missing out" on being close to his Australian family.
