Jennifer Aniston bans Justin Theroux's ex from their wedding
The Friends star was upset because the 41-year-old had previously persuaded her not to invite any of her own former flames.
A source tells Now: 'He must've had a "brain fade" moment.
'Jennifer hit the roof when she saw that he'd put Heidi on the guest list.'
Jen, 43, has now put her foot down.
'Justin argued that Heidi's been part of his family for many years,' adds the source.
'That seemed to help resolve things because now they've agreed no exes are to be invited.'
