MIRANDA Kerr's mum has gone into direct competition with her daughter, 10 months after she was ousted from the supermodel's skincare company.

With reported tension ­between the pair, Therese Kerr, the former general manager of Kerr's Kora Organics, has launched her own beauty range.

"Miranda wanted to keep Kora as a skincare range, but I said: 'You know what? I want to share certified organic goodness with the world'," Mrs Kerr told The Sunday Telegraph.

It's a bold move by Mrs Kerr, who was ­instrumental in helping ­establish Kora. Her exit from the company in January came as a shock.

Mrs Kerr's new range, Divine By Therese Kerr, includes certified organic products such as ­deodorant, toothpaste, hand sanitiser, mouthwash, hand wash and hand lotion and will be launched nationally in February.

And two months after that she will extend her range to include hair care and baby products.

"I'm really proud of Mum for creating this range," Kerr said. "There is definitely a gap in the market for certified organic personal care products. She is passionate and dedicated and I know it will be a huge success for her."

Speculation that mother and daughter pair have had a falling out was revealed in The Sunday Telegraph earlier this year when Mrs Kerr stepped down from her position at Kora Organics.

She then posted a cartoon on her Instagram site showing a ­mother hen pointing at a baby chick with the words: "I sat on you and brought you into this world and I can sit on you and take you out."

Mrs Kerr insists the move isn't a bid to compete with her daughter.

"It is to compliment the Kora range," she said. "Miranda is really excited, which is wonderful. I would envisage we will end up having the ranges as mum and daughter beside each other in stores."

Of leaving Kora to start her own range, she said: "I stepped down from that position because I wasn't walking my walk in ­regards to health and wellness.

"I was working too many hours a day and not having that balance I needed and that combined with stress, it got too much. It is what it is and I live life to the fullest and now I have found my passion and it is divine."

Kerr, 30, has endured a difficult year, losing high-profile modelling contracts.

The mum-of-one was replaced as the face of David Jones by Jessica Gomes, stepped away from Victoria's Secret and lost her Mango contract.

In her personal life, the supermodel announced her separation from husband Orlando Bloom and is now dating James Packer.

Sources say Mrs Kerr and her daughter fell out over business dealings and the model's "micro-managing".

Interestingly, in a recent Harper's Bazaar article, Kerr credited her grandmother with her success and not her mother.
