Poor Chris...he's heartbroken. I think Ally chose Roberto for the wrong reasons and couldn't see the obvious match for her was Chris. From show #1, she was infatuated with Roberto's looks, and never thought she would have been able to date such a good looking guy. She's just looking for a fairytale and couldn't see the real-life Prince (Chris) right in front of her.
And for the record, yes Roberto is sexy. But Chris is smokin' hot
