Even though many of you have been introduced to Karmin, the pop duo still want to say "Hello."

On Tuesday (August 7) YouTube sensations Amy Heidemann and fiancé Nick Noonan released the video for "Hello," the second single off their debut album of the same name, which was released in May. The clip shows Heidemann rapping in her daisy dukes as she journeys throughout Chinatown on a Beach Cruiser. Meanwhile Noonan gives himself a brand-new look as he shaves off his golden locks in anticipation of a date with his other half. The two reunite at the end of the video as Noonan picks up Heidemann in a classic convertible and they drive off in style.

MTV News recently spoke to Karmin, who are competing against newcomer Rita Ora in a fan voted contest to land the cover of Rolling Stone's first ever "Women Who Rock" issue, and they told us the concept behind the video.

"It's mostly performance-based and we do it in Chinatown in L.A., that's where it was filmed," Noonan said. "It's very cool ambiance, a lot of cool visuals and it's kind of like our coming-out party. 'Brokenhearted' was obviously very successful for us, went platinum last month or two ago, so there is kind of like, 'Hey, we're Karmin, nice to meet you.' That's the idea."

The Stargate-produced track shows off Heidemann's impressive rapping skills as she flows over a catchy beat about their rise to fame and the people who doubted them along the way.

"We wanted to kind of hold on to this one until the world had a better idea of who we were, and I think 'Brokenhearted' really helped establish us as artists," Heidemann said. "This one gets a little darker, the sound is darker, there's more rap in it, it's a little more aggressive."

Karmin, who were first discovered through YouTube after posting successful cover videos including Chris Brown's "Look at Me Now," feel that "Hello" will remind fans of why they fell in love with them in the first place.

"It's kind of more of the 'Look at Me Now' hip-hop roots, all the videos that blew up with all the rapping," Noonan said. "So we kind of get back to that a little bit here. It's fun. It's one of those songs I've been listening to for like 10 months and I'm still not sick of it yet, so hopefully that's a good thing. "
