He probably likes em thicc.
Brehs into big girls are also attracted to average sized broads but dudes into thin/lean broads (usually) only like that type. He was into her no matter her size.
60? She honestly doesn't look bad for a white woman at that age. Heavy, sure but she doesn't look tired and haggard. PB is smart...leave the young broads alone. He already has 5 kids...he doesn't need to become a new daddy again at damn near 70.
Also....he's not leaving her based on this from Reddit:
"Brosnan is a stand up guy. He adopted his first wife's kids. He was a rock when she was dying of cervical cancer. Always treated those kids like his own even when he later remarried. Then took care of his adopted daughter as she was dying of the same kind of cancer that killed her mother. His first wife was also older than him and people always tried to make an issue of it."
