Scott Porter gained worldwide recognition for his dramatic acting chops after playing sidelined QB1, Jason Street, on NBC's Friday Night Lights. But before he donned Dylan blue, Scott's singing voice echoed in the rafters when he played Matthew in the Off-Broadway production of Altar Boyz. In fact, his resume is littered with roles that hint at his musical tendencies (Bandslam, Music & Lyrics, Call Me Doctor) -- and on tonight's Hart of Dixie, Scott's singing voice makes its primetime premiere!

Following up on last week's emotional episode (Lemon's affair came to light and George called off their wedding), Scott hits the karaoke stage when George sets out on an impulsive trip to New Orleans ... with Zoe in toe!

I chatted with Scott about this interesting turn of events for his character and found out what it means for the final four episodes of the season. Plus, Scott broke down his now infamous turn as a "video ho" and lets you in on his Ultimate Karaoke Playlist!

Insider.com: What did you make of George's somewhat stoic reaction to learning of Lemon's affair?
Scott Porter: I thought it was the only thing he could do. If you look back over the course of the season, there's been lots of subtle moments where George catches Lemon's doubt but tries to fix her – he's been searching all year because he felt like something was off. And when he finds out just how bad it is, what a terrible thing she's done, he can't do anything but walk away. All his fight is gone because he's been fighting all season to make things right, but he had no idea what he was actually up against.

Insider: In that moment did George feel like, "Finally, it all makes sense!"
Scott: In a way. On the day we were shooting, we thought him quietly taking it all in was the most realistic reaction. He understands now, but it forces him to re-evaluate all of his relationships – George is really bothered by the fact that everybody knew and no one told him. He doesn't know who he can trust any more, so he's got to walk away and reevaluate everything he thinks he knows.

Insider: Previews show a very smiley, happy George in tonight's episode. Is he in denial?
Scott: George is so intent on fixing everything and helping everyone that he's never really thought about himself. He's very selfless, which is his greatest fault. So he goes home that night and wonders, "Where did helping everyone else get me? Crushed and lied to and betrayed." So he says to hell with everything else and is going to do what George wants to do for the first time ever. So he wakes up with a smile on his face, goes out into the world with this "Whatever I Want" attitude. Visit New Orleans? Yes! Buy a motorcycle? Sure! He does all these crazy things – It's like Brewster's Millions. It's time for George to have his say. It's fun where this takes him and it'll be great for audiences to see this side of him.

Insider: Well, as readers just saw, it takes him to the karaoke stage. Were you excited to showcase that side of you in the episode?
Scott: Absolutely. Wilson [Bethel, who plays Wade] has recorded some songs for the show, Jaime [King, who plays Lemon] had already sung -- I'm so glad we've all been able to show the audience how multi-faceted we are. Next, we have to get Rachel [Bilson, who plays Zoe] and Cress [Williams, who plays Lavon] to duet.

Insider: Well, we all have seen Rachel's rapping skills thanks to Call Me Doctor. How much fun was that to make?
Scott: [laughs] It was amazing. It was kind of Wilson's baby – he and Rachel spend a lot of time together because their characters do, so they hatched this plan and Wilson called me about being a "video ho." He wanted two dudes in the tightest jeans imaginable, wearing tank tops and washing a car. On the day, I called him and asked if I needed to bring a change of clothes, and he said no. "No one’s gonna get wet." But I knew better because in the moment, things just got crazy. The great thing about working with Wilson is he's not afraid of going too far – and neither am I. That video is the proof of what happens when you put two people who aren't afraid of going too far in front of a camera.

Insider: George sings Jambalaya in tonight's episode -- what are your go-to karaoke songs?
Scott: I have karaoke songs for every genre – Stevie Wonder's Superstition, Open Arms by Journey, Bottoms Up by Trey Songz. I'm all over the place. I have a stable of numbers. You collect them over time. I'm a big karaoke singer.

Insider: Looking at these last four episodes, what are you excited for fans to see?
Scott: I'm excited for fans to see different sides to all the characters. I think one of the things that's been so endearing about Hart of Dixie is the speed at which we've gone. It's a much slower pace than most other TV these days, but because of this secret being out there and this rapidly approaching wedding date, the speed picks up a lot in the final episodes. George is a fixer and it would be out of character for him and Lemon to not try and fix their relationship. But is it too big a mountain for them to climb together? I'm excited for fans to get the answer to that. Every relationship has changed because of last week's episode – I think fans may have missed just how much Zoe and Wade's relationship changed because of what he said. That door has been slammed. Zoe is all alone now. I think the payoff will be spectacular for fans.

Hart of Dixie airs Mondays at 9 p.m. on The CW.
