Harry Styles Supports Zach Braff's 'Wish I Was Here' Premiere at Sundance

Kate Hudson and Ashley Greene join the One Directions member to support the crowd-funded comedy drama in Park City, Utah.

Harry Styles was among the celebrity guests at the premiere of Zach Braff starrer "Wish I Was Here" at Sundance Film Festival on Saturday evening, January 18 at the Marc Theatre in Park City, Utah. The British heartthrob was mobbed by One Direction's fans at the event.

The 19-year-old boybander donned a casual sweater and jeans combo topped with a navy Saint Laurent coat from the other night when he watched Eagles' concert in Los Angeles. "Today I watched @WIWHFilm. I wasn't crying, I had sweaty eyes. Loved it," he tweeted.

Kathy Griffin, who was seated next to Harry at the concert, previously boasted that she stole the teen star's coat while he was distracted by Kendall Jenner and even posted on her social media a picture of herself wearing the coat. "U know where to find me...," the anchor joked.

Harry came to the Sundance Film Festival without his rumored lady love though. He was joined by Zach and his beautiful co-stars Kate Hudson and Ashley Greene. "Congratulations to @zachbraff and @BraffAdam on a lovely movie.. They're brothers," the young singer wrote.

Directed by Zach and co-written by the "Scrubs" star and his brother Adam Braff, the comedy drama follows a struggling actor, father and husband who is trying to find the purpose of his life at the age of 35. The Kickstarter-funded pic is acquired by Focus Features with approximately $2.75 million.
