Jennifer Lopez and Marc Anthony are reportedly showing "signs of a possible reconciliation".

According to American website TMZ, the estranged couple weren't talking "months before the breakup" and were often involved in tearful arguments.

However, following their shock split last year, the pair have resumed communication and are getting along well.

"Months before the breakup, there was virtual radio silence between the two. We're told when they did talk, it was loud and contentious... often ending in tears on Jennifer's part," TMZ reports. "But since the split, we're told their bond has materially strengthened. They are communicating and co-parenting well and not fighting at all."

Jennifer and Marc separated after seven years of marriage last summer.

According to the website's sources, the Latino star and her estranged husband are happy to work together on their talent show Q'Viva as well as joint charity work.

Reports of their thawing relations could be backed up by a recently published picture that showed Marc placing his hand on Jennifer's lower back in a friendly manner.

"A number of people around them are saying there are signs of a possible reconciliation, although it is by no means certain," TMZ added.
