These led to a regular role in the Cartoon Network TV series '' Out of Jimmy 's Head '' in 2007 – 2008 and a recurring role on '' Two and a Half Men '' in 2008 – 2009 . Although she was uncredited in the poorly received '' Masked and Anonymous '' , Roger Ebert observed at the film 's 2003 Sundance Film Festival premiere " the one performer in the movie whose performance actually was applauded ; that was a young black girl named Tinashe Kachingwe , who sings ' The Times They Are A-Changin '' with such sweetness and conviction that she is like a master class . " He concluded his review of the movie : " If I had been asked to serve as consultant on this picture , my advice would have amounted to three words : more Tinashe Kachingwe . " In 2007 , Tinashe joined girl group the Stunners , founded by Vitamin C . Her bandmates were friends Marisol Esparza , Allie Gonino , Hayley Kiyoko , and Kelsey Sanders . Six months after their formation , the group signed with Columbia Records , and later signed a production deal with Lionsgate Entertainment for scripted television show for MTV . On March 18 , 2009 , they released a single and video , " Bubblegum . " In October , the group released a five-song EP , influenced by artists such as Madonna , Gwen Stefani , and Rihanna . The music video for their promo single , " We Got It " , was released on February 22 , 2010 , and they performed the song on '' The Today Show '' and '' The Wendy Williams Show '' . After signing with Universal Republic Records in 2010 they released a single , " Dancin ' Around the Truth . " The music video premiered on June 2 , 2010 , just before the group was announced as an opening act on Justin Bieber 's My World Tour
