Bella Thorne Guesses the Brand at Just Jared's Halloween Party with Boyfriend Tristan Klier!

Bella Thorne and her on-again boyfriend Tristan Klier are all about peace and love while dressed as hippies after stopping by the Brand X booth at the 2014 Just Jared Halloween Party: “JJ Freak Show” held at No Vacancy on Friday (October 31) in Hollywood.

The 17-year-old actress was joined at the party by Sofia Richie, who looked fabulous as Khaleesi from Game of Thrones, and Cameron Monaghan, who channeled Patrick Bateman from American Psycho – complete with a bloodied knife!

Also in attendance at the big bash were Young & Hungry‘s Emily Osment (dressed as Cruella Devil) and her date for the evening, Mallory Jansen (as Audrey Hepburn), and actress Francia Raisa (dressed as Rosie of Sophia Grace & Rosie from The Ellen Show). Just Jared‘s Jared Eng also got in on the fun with the guests – he dressed as a shirtless ringmaster.

While at the event, Bella stopped by the What Brand Is It? booth for a chance to win $25,000! Even better – now you can have a shot at winning big bucks! Get all the details here.
