She fears Kevin just wants to promote himself at her expense to further his career."This is not the first time the couple have had disagreements over Kevin's ambitions to become a star in his own right.The 28-year-old former dancer recently said he was tired of being overshadowed by his famous wife and could not wait to be respected for his talent.
