Dylan Minnette says he felt 'awkward and embarrassed' singing to Amanda Seyfried in 'The Dropout'

• Dylan Minnette told Insider that it was not his "number one choice to sing on camera."
• The "13 Reasons Why" actor plays Theranos whistleblower Tyler Shultz in Hulu's "The Dropout."

"13 Reasons Why" star Dylan Minnette spoke to Insider about his "really nerve-wracking" singing scene in "The Dropout."

The actor stars as Tyler Shultz in Hulu's drama series, which details the rise and fall of health start-up Theranos and its founder Elizabeth Holmes, played by Amanda Seyfried. Shultz was one of the most prominent Theranos whistleblowers and played a key role in the company's downfall.

In the series' sixth episode, titled "Iron Sisters," Shultz attends Holmes' birthday party where he sings an original song about Holmes directly to her. According to Minnette, that really happened between the real-life Shultz and Holmes.

"That was a real event, which is so insane. It's truly one of the weirdest moments of the whole show," the singer, who's in an alternative rock band called the Wallows, told Insider.

"For me, I'm so used to singing in front of people but it was really nerve-wracking," Minnette added. "It's not my number one choice to sing on camera. That's not something I was seeking out."

Although the actor said he "was nervous" and "very embarrassed," he noted that it helped that the writers had penned "an amazing song written for it that was just hilarious and awkward and somewhat charming, too."

Minnette said that it didn't help that his costar, Seyfried, was playing Holmes true to character. The entrepreneur was known as a person who "rarely blinks."

"I felt so awkward and embarrassed and Amanda, even off-camera, was just staring at me deep into my soul. At times she was trying to make me laugh, too," he recalled. "She made it enjoyable but also put so much pressure on me intentionally just to sort of mess with me."

"The Dropout," also starring William H. Macy and Elizabeth Marvel, streams on Hulu.
