Bella Thorne knows a thing or two about dating in Hollywood, but don't expect her to write a rule book anytime soon!

ET caught up with the 19-year-old actress at the Freeform upfronts in New York City on Wednesday, where she opened up about dating in the spotlight -- and admitted that she still "can't figure it out."

"I think there are no rules," said Thorne, who was previously linked to Charlie Puth and dated Tyler Posey. "But I literally have no idea. I can't figure it out myself."

The Famous in Love star is single these days, but she's still the subject of crazy rumors.

"People say that I don't eat and I just think it's so ridiculous," she shared. "If you follow me on Snapchat, anybody that knows me is like, 'I've never known a girl who eats as much as she does.' I just work out a ton, but I haven't worked out in a while, so don't look at me."

Despite what she may think, Thorne's body is still on point. The actress showed off her abs beneath a fishnet bodysuit in a look she put together herself.

"I styled myself this whole trip, and I just kind of picked what I liked best," she revealed. "I went on Dolls Kill and they have some funky sh*t that I like, that's kind of out of pocket and cool, and I just kind of put it together."

Thorne spoke more about her dating life with ET in January, declaring that "dating in Hollywood is literally the worst thing." 

"People are really crazy on social and, unfortunately, I date people that have girls, like, in love with them," she explained. "They're, like, really in love with them and they want to kill me. Literally, I was getting death threats, full-on death threats on Twitter."
