Looks like Ben Affleck's rumoured affair with nanny Christine Ouzounian has shattered Jennifer Garner as she considers it to be the biggest betrayal.
A source, who claims to be friends with Ouzounian, said that the 43-year-old actress was livid when she heard the rumours, reported People magazine.
According to the source, the 'Alias' star said that if her children are close to the nanny and she does this it is the biggest betrayal.
Clearing up that the nanny was not responsible for the couple's split, the source said that there was no affair during their marriage and Ouzounian is not the reason for their separation.
The duo announced the news of their separation in July, thereby ending their ten years marriage.
