After getting coffee with hubby Ben Affleck earlier in the day, Jennifer Garner spent some quality time with the other man in her life: baby Samuel! The 8-month-old was very eager to get his hands on the doll she was holding ... he's a feisty one!

While Ben seems to have an endless amount of films that he's working on, we're thinking Jen might want to pay a few visits to the set of his upcoming flick Focus, as Kristen Stewart is reportedly in talks to star as the hunky actor's love interest!

Focus follows "a veteran con-man (Affleck) who becomes romantically involved with a newcomer (Stewart) and finds the relationship challenged by their illegal activities. When they meet again down the line, the complications have long-lasting effects."

You know what K. Stew is capable of ... and Ben is infinitely hotter than Rupert Sanders, so watch out Jen!
