The 'Words' actress - who reconciled with Bradley in September after splitting in March - was spotted deep in conversation with Gloria Cooper on Friday (23.11.12) as they enjoyed a day out with the actor and his dog in Venice, California.
A source told RadarOnline: ''Bradley was standing with his dog outside the Mystic Journey Bookstore, while his mother and Zoe were inside shopping. The two women were engrossed in deep conversation, it looked very serious, and there was clearly a lot of bonding going on.''
Bradley is so smitten with Zoe that he recently turned down burlesque beauty Dita Von Teese when she made a pass at him.
The dancer was seen making eyes at 'The Hangover' actor at Farfalla restaurant in Los Angeles and tried to buy a drink for the handsome star, but he remained immune to her advances and left without saying goodbye.
An onlooker said: ''Bradley completely snubbed Dita when she made a beeline for him. She was desperate to get his attention, so she asked the waitress to go over to his table and ask him what he wanted to drink.
''Bradley told the waitress he's on a health kick at the moment and said he was fine. After that, Dita was looking over at him, fluttering her eyelids and wanted him to join her and her friend.
''But Bradley just wasn't that into her, he ignored her eye contact and just looked down at his phone. He left before she did and didn't even acknowledge her on the way out of the restaurant.''
