Teddi Mellencamp’s battle with brain cancer has taken a further devastating turn – with the reality star said to be preparing her children ‘for the worst.’

The Real Housewives of Beverly Hills alum, 43, who previously said she felt she was on her ‘deathbed’, has already undergone more than 20 surgeries during her two and a half year cancer battle.

She was initially diagnosed with melanoma but now it has spread and she recently underwent surgery to remove four tumors from her brain.

Earlier this month, more tumors were discovered in her brain and lungs which has caused the daughter of rocker John Mellencamp to face the reality that her daughters Slate, 12, and Dove, five, and son Cruz, 10, may have to face life without her in the very near future.

‘Teddi is a fighter – anyone who has watched Real Housewives can attest to that,’ Radar reported.
