Benji Madden and Sophie Monk spent some time in Vegas last weekend. To recap, Benji Madden is Nicole Richie’s Baby Daddy’s brother,  and Sophie Monk is a hot actress from Australia (and Benji’s main squeeze). Are the two just comfortable with each other, or does he have a wandering eye? Reports indicated the two barely spent any time together in the Bellaggio nighclub as Benji wandered around posing for pics and Sophie danced by herself. Once again, only time will tell.
