"My fans can expect to embrace my versatility and growth, professionally and personally. I am truly excited to share my new album with my fans. I worked with wonderful artists..." "It is a blessing to be a woman in the hip-hop industry to be able to put out a fifth album under my career."
The album's official cover art was revealed on March 26, 2010. The vocals of Lady Gaga, who also co-wrote "Let Dem Hoes Fight", were replaced by Kalenna of Dirty Money, due to issues with Gaga's record Label.

It sold more than 32,000 copies in its first week. As of May 2011, the album has sold 100,000 copies in the United States.
An album preview was held on February 19 where critics were able to preview 10 of the 15 tracks to make the album. Many critics complimented on the album's preview stating "Amazin' is catered for the dance floor – something that Trina stated she wanted to hear when she’s getting her sip on at the club. Though we only heard a few minutes of each track, it’s a lot less explicit than usual fare – a sign that Trina might be growing up."
The album was first revealed on Trina's official Myspace page. Along with singles being released for promotion, Trina released two mixtapes to commemorate her fifth LP. One is named after the album, Amazin' (The Mixtape), and the other after the first lead single, Definition Of A Million Dollar Girl.
