A report claimed that the relationship between the two ended shortly before Hamm started his alcohol treatment in February. It further claimed that the split was prompted by the uncertainty of their relationship in the future.
Hamm's representative, however, rebuffed such reports and said 'public's understanding and sensitivity' were highly expected, reported Aceshowbiz.
"The story that appeared in this week's edition of In Touch magazine is not true.
"The only gentleman Jennifer visited regularly in Connecticut was Jon, while he was in rehab. They continue to ask for the public's understanding and sensitivity during this challenging time," the representative said in the statement.
