Bella Thorne being Bella (see-thru bra, various piercings)
Sometimes female celebrities manage to overcome average looks to achieve intense sexiness: Ellen Barkin and Lady Gaga come immediately to mind.
Bela Thorne is the opposite of that. She has an attractive face and an absolutely spectacular figure, but usually manages to look like she just got out of bed on the first day of rehab. She joins Helena Bonham Carter and Norman Reedus on the list of potentially beautiful people that you would assume to be homeless if you ran into them.
