The First single, "No Panties", featuring Tweet was released on May 21, 2002 but only reached number eighty-eight on the Hot R&B/Hip-Hop Songs chart. However, it became her first single to chart outside of the US, as it reached number forty-five on the UK Singles Chart.
The Second and final single from the album, "B R Right", featuring Ludacris, was also released on September 8, 2002 and reached number eighty-three on the Hot 100, number fifty on the Hot R&B/Hip-Hop Songs chart and number twenty-four on the Rap Songs chart, becoming a fairly successful single.
Billboard says,"Trina enlists a cast of all-stars and newcomers in crafting this, her sophomore set. On the Missy "Misdemeanor" Elliot-penned and co-produced lead single "No Panties," the Miami native is joined by Tweet; both ladies ably lay down the law as they see fit, deftly telling men what women need to be happy. On "Kandi," Trina introduces her own version of "mini-me"—a young 10 year old female emcee named Lil' Brianna. The two make for an adorable and cute duet that samples New Edition's 1983 hit "Candy Girl". The autobiographical "U & Me" finds Trina standing on her own. Produced by Cool & Dre, the song serves as the album's most profound moment, with the artist taking a serious look at the ups and downs of rap stardom. Though not perfect, Diamond Princess proves that Trina, like the album's gem namesake, is pretty, shiny, and stronger than you might think."—RH
