London, Jul 4 (ANI): Even though fellow ‘The X Factor’ judges Cheryl Cole and Dannii Minogue are said to be rivals, friends were surprised when the two appeared amicable at Cole’s birthday bash.

But Cole, who turned 26 on June 30, has been revealed to harbour insecurities about how her relationship with 37-year-old Minogue will fare over the coming weeks.

The ‘Girls Aloud’ member is so anxious that she does not upset Minogue that she even has her footballer husband Ashley Cole concerned.

“After her birthday party, Cheryl was feeling tired and emotional and told Ashley how much she loved and needed him,” the Daily Express quoted a source close to the footballer as saying.

“She was feeling incredibly vulnerable after spending so much time around Dannii. Though there is no out-and-out feud, there is always going to be competition between the pair.

“Ashley worries because Cheryl always takes things to heart.

“She’s incredibly sensitive, prone to depression, and liable to thinking any hint of bad blood between her and Dannii must be her fault,” the source added. (ANI)
