New York, December 24: American actress/singer Jennifer Lopez might have renewed her wedding vows with her husband Mark Anthony recently, but it seems that they have been facing troubles in their relationship for long.

While the couple were recently photographed without their wedding rings, sources have revealed that Lopez used to take all necessary steps to ensure that her husband did not cheat on her during his tours.

A source has revealed that Lopez would send her assistant with Anthony on tour, while she stayed at home with their twins, so as to remain informed about her husband's moves.

"She wanted reports back so he didn''t cheat on her," the New York Post quoted the source as saying.

The newspaper also revealed that the couple were selling their 8.5million-dollar Bel Air estate, where they exchanged wedding vows in June 2004.

Representatives for Lopez were unavailable for comment. (ANI)
