Big Bang rapper G-Dragon has reached the height of hip-hop credibility, with legendary performer and producer Missy "Misdemeanor" Elliot featured on a track on his second solo album second solo album, to be released on August 18.

YG Entertainment record label founder and CEO Yang Hyun Suk officially revealed the Missy Elliot and G-Dragon collaboration on Monday.

"With the second solo album, what we decided to do was to have one legendary foreign artist featured on it rather than have several," Yang wrote.

"There were many male rappers on the list, but what YG was looking for was a female rapper, and there was just one. We found the answer so quickly and we were unanimous on choosing this artist. And she is Missy Elliott. If you know a tiny bit about hip-hop, you would know this legendary artist."

Yet for any Missy Elliot fans that closely follow the star's Twitter page, the announcement was old news.

Missy blew the lid off of the G-Dragon collaboration back in January, when K-pop journalist Tracy Cozette asked her about it on Twitter, according to the website YG United.

"@MissyElliott I'm gonna need your track with [G-Dragon of Big Bang] like tomorrow!" Cozette wrote. "I'm too hype. It's gonna be colossal."

"@TracyCozette funny I did a record with [G-Dragon of Big Bang]," Elliot responded. "I don't know if they got my vocals. This was last year."

When fan Ghetto Adzz pressed her for details, the rapper and singer gave away a detail even YG Entertainment has yet to discuss.

"It was supposed to be a record with me and Ludacris up there too," Elliot tweeted.

And although YG hasn't mentioned the Ludacris collaboration yet, G-Dragon's representatives confirmed it in March of 2012 to the website Soompi.

Apparently the recording has been in the pipeline for quote some time.

"Ludacris and G-Dragon completed their work together last year," G-Dragon's representative said.

"Ludacris will be part of G-Dragon's new solo album scheduled for this summer. He took the rap featuring part for a song written by G-Dragon. Since a world-renowned rapper joined hands with G-Dragon, you can look forward to it."

Not only will G-Dragon's August 18 album release date mark the four year anniversary of his debut album "Heartbreaker," it will also be the rapper's 25th birthday.

The collaboration between he and Ludacris reportedly happened because the Atlanta rapper asked to work with G-Dragon during a trip to South Korea in 2011.
