Now she's behind bars after police say she set her boyfriend's condo on fire.
It happened in Tempe near Southern and Kyrene.
Police say they're not exactly sure what set Claudia Drinnan off. Witnesses told officers she was mumbling about her boyfriend cheating on her when she got to his place at 1:30 in the morning.
He wasn't home, and that's when investigators say she started a fire in her boyfriend's room.
She was handcuffed and wearing a white jumpsuit, 21-year-old Claudia Drinnan did not say a word as she was booked into jail.
Drinnan's Facebook page says she is an ASU student majoring in non-profit management. Her boyfriend's roommate says he heard someone bang on the house and then he heard glass break.
"I've only seen this stuff out of a movie, I've never seen or heard of a female setting her boyfriend or ex-boyfriend's room on fire," said Kevan Walker.
Kevan Walker said he saw Drinnan climb into the window of her boyfriends room, and then locked herself inside. 15 minutes later he smelled smoke.
"Scariest part of the whole night is when I came outside, the flames were coming, she was standing at the entrance and I asked her what are you doing? She was just staring at the fire, she wasn't looking at me, she wasn't replying to my comments, she was staring at the fire, no body motion or anything, that was the scary part for me," said Walker.
Walker said he never though Drinnan would do something like this. In a YouTube video she made for a class project, Drinnan says she's volunteered since she was 10-years-old.
"I'm just happy that I'm alive, to be honest, I've never been in a situation like this, so I feel blessed, and I'm just happy that nobody was hurt," he said.
Drinnan is now facing felony charges of arson, endangerment, and burglary.
