Ashley helps Cheryl prepare for climb

Ashley Cole is reportedly helping wife Cheryl prepare for her climb up Mount Kilimanjaro later this month.

The footballer is said to be concerned that the X Factor judge may suffer from headaches or dizziness as a result of the high altitude on the Comic Relief expedition, Now reports.

A source said: "Ashley's been doing lots of stretching with Cheryl and getting her the best vitamins and minerals, which supplement her new diet.

"He's also helped source the equipment she uses, so she has the best sleeping bag, rucksack and boots available."

The source added that the Chelsea and England player is worried that the couple could become divided if Cheryl gains "new strength and vision" by completing the trek.

Cheryl recently admitted that the climb will be a "real personal challenge" for her and Girls Aloud bandmate Kimberly Walsh.
