Barbie met Robbie in early December while getting a latte. Madison went to see Robbie's band on the 6th of November. He stared at Barbie because he thought she was attractive, but he saw her flirting with another guy. Madison thought it was hilarious because she considered Robbie to be beneath Barbie due to him being self-centered.
Robbie became Barbie's boyfriend at some point after this. On the 8th of March, Madison wrote that Barbie was upset because Robbie would be leaving New York, so Madison cheered her up.
