Nick, 39, is reportedly playing a reality TV star in The Coop, an eight-episode interactive series made in partnership with Funny or Die, which creator Nora Kirkpatrick told the magazine is like when Big Brother meets the game Clue.
Although Nick tends to be self-deprecating about his acting gig, Nora insisted he's selling himself short.
"He was wonderful and very talented. A joy to work with," Nora revealed. "He was there on set 100 percent as an actor. He did a wonderful, wonderful job."
Nick said he looks forward to the day when his accomplishments outshine gossip about his dating life.
Nick told Us that he's waiting for the day when "people care more about my acting career or podcasts or other things I'm doing rather than who I'm not dating."
"That would be great," noted Nick, who sparked dating rumors in July when he and Rachel Bilson exchanged flirty messages on social media.
