The pair's relationship on the talent competition was so bad it resulted in Osbourne being forced to quit.
But with rumours that Sharon, 58, could be set to make a return to the judging panel, Dannii has said she is no longer worried about their feud.
Speaking at the Australian Open, she told British newspaper The Daily Express: 'I'm not worried about Sharon going back - it's up to them to recruit whoever they want.
'The X Factor is a great show and I thought I had a great year last year.'
The pair began feuding when they sat on the judging panel together in 2007 and their argument was reignited last year when Minogue claimed in her autobiography that Osbourne bullied her.
But it seems like the 39-year-old becoming a mum to six-month-old Ethan with partner Kris Smith has chilled her out.
She added: 'I'd definitely recommend motherhood. I've never been happier and my life is complete with Kris and Ethan. We are a very happy family.'
