Michael Trevino, who plays Tyler in the series, captured the moment last week on Instagram with the caption, "About to see our girl @ninadobrev new movie Let's Be Cops! TVD came to represent! #TVD "
Zach Roerig (Matt) and Michael Malarkey (Enzo) also joined Trevino to support Dobrev in her new endeavor.
According to some reports, Somerhalder decided to skip the premiere to avoid unnecessary awkwardness on her big day.
Somerhalder is currently dating Nikki Reed and is apparently thrilled with his new relationship.
“I couldn’t be happier if I tried,” Somerhalder told E! News at the 2014 Creative Arts Emmys.
Friends couldn't agree more.
"[Nikki and Ian are] smitten with each other and love spending time together," an insider said.
A few weeks ago, Somerhalder posted a photo of himself with his new horse and thanked Reed for snapping the shot: "Proud new dad... What amazing creatures they are. Wow. His name is Eagle. Thank you @iamnikkireed for snapping this special moment, with our big baby boy."
Let's Be Cops was released in theaters on Aug. 13.
