Looks like Shania Twain and Robert “Mutt” Lange can’t keep their divorce private for long — only days after announcing their split comes news that Mutt Lange’s affair with Marie Ann Thiébaud is to blame.

Marie Ann Thiébaud was Robert Lange and Shania Twain’s secretary — reports are that Mutt and Marie Ann Thiébaud have been having an affair for some time now. Marie Ann Thiébaud is also married.

Mutt Lange has commented to People magazine that his relationship with Marie Ann Thiébaud is “absolutely not the reason [for the separation]. It’s not true.”
