Both Zac and Max donned button-ups and a polished 'do, while Emily opted for sophistication in an ivory turtleneck frock featuring black thigh high boots.

Things started out nicely when the interviewer addressed the rules of the game, but things took a hilarious turn when Zac was put on the hot seat.

The intro to various songs were played without any lyrics being heard, leading the stars to fend for themselves with the hopes of remembering the name of the jam.

Zac first suggested 'Soaring and Flying,' as the song title before hearing an uproar of laughter, which he defended himself by noting: 'There's like three movies of songs guys, come on!'

Emily, on the other hand, immediately nabbed Beyonce’s Drunk In Love before Max inadvertently knew of the title EDM-inspired track from their flick We Are Your Friends. 

No idea: It appears the trio are not fans of the boy band One Direction, considering their confused expressions when hearing the intro to Steal My Girl

Zac dished about the 1D song: 'I would never know that, sorry about that,' which got both Emily and Max giggling at his quick shutdown of the popular teen heartthrobs.

He was quickly complimented by the model when he landed the 1995 Spanish dance classic, Macarana by Los del Rio.

Robin Thicke's 2013 hit single Blurred Lines was played last and Zac remained befuddled, even though the video vixen starring in the music video was sitting right beside him in silence. 

Max yelled out the correct title, which brought a smile to the brunette beauty's face.

Zac showed his embarrassment, but did so with pride and confidence, noting: ' Not knowing the names of Blurred Lines and High School Musical...I think we nailed it.'

Emily made him feel better about his mistakes by jokingly addressing: 'You're trying to focus on your craft.'

Dream team: The Blurred Lines vixen and Zac were last spotted on Friday in San Francisco continuing the promotion for their upcoming film, slated for release August 28

Zac stripped down to just his T-shirt, deciding to remove his leather jacket after breaking out in a sweat at the tour after party.

Emily also dressed down for her visit to the club, wearing a sleeveless white top and beige trousers.

We Are Your Friends marks Max Joseph's feature film directorial debut and the movie is about an aspiring DJ named Cole trying to find his own signature style in the EDM scene.
