Bella Thorne Brings Ex-Boyfriend Tristan Klier to 'Alexander' Premiere

Bella Thorne is a orange beauty as she poses with on-and-off boyfriend Tristan Klier at the premiere of her new movie Alexander and the Terrible, Horrible, No Good, Very Bad Day at the El Capitan Theatre on Monday night (October 6) in Hollywood.

The 16-year-old actress was also joined on the carpet by her co-stars Steve Carell, Jennifer Garner, Dylan Minnette, Kerris Dorsey, and Ed Oxenbould.

Kerris‘s sister Justine was also in attendance for support.

Here’s the film’s synopsis: Alexander’s day begins with gum stuck in his hair, followed by more calamities. Though he finds little sympathy from his family and begins to wonder if bad things only happen to him, his mom, dad, brother, and sister all find themselves living through their own terrible, horrible, no good, very bad day.

FYI: Bella is wearing an Alberta Ferretti dress, Stuart Weitzman shoes, Neil Lane jewelry, and an Edie Parker clutch. Kerris is wearing Contrarian New York.
