Rumours that Klum had embarked on the new relationship began circulating on Friday, after which Seal claimed that she lacks "class" for "fornicating with the help" before they were officially separated.
The Project Runway host later hit back at the claims via her rep, who said: "It is sad that [he] has to resort to false accusations."
Seal's spokesperson has now spoken out to defend the 'Kiss From a Rose' singer's original comments.
The rep told Us Weekly: "Seal would like to clarify that he was not implying his wife was cheating while they were together, but he was merely pointing out that their separation and divorce were not final and they are still legally married."
Seal and Klum ended their marriage in January 2012.
