Shane Warne involved in 'another break-up'

Shane Warne, who is believed to have ended his relationship with Elizabeth Hurely, has been involved in another break-up - only this time it was a business affair.

The spin king and his long-time personal assistant Helen Nolan have parted ways after five and a half years.

Nolan, who rarely gives interviews, said she was exhausted dealing with Australia's most in-demand celebrity.

"I've been that emotional this week since telling Shane, because I am just so exhausted," the Herald Sun quoted Nolan as saying.

"I just can't do it any more. It's not Shane, it's everything that goes with it.

"After five and a half years years it was a great innings. But I just need a break," she added.
