Jackson 'too loyal and giving' for marriage

Janet Jackson fears she is to blame for the failure of her marriages to Rene Elizondo and James DeBarge - because she was too loyal and giving.

The r n'b superstar continues to dismiss reports she and producer boyfriend Jermaine Dupri have wed in secret, and now suggests she may never marry again - because she worries she will jinx a romance if she takes on another husband.
