50 Cent's new album, "Curtis," has been pushed back another week from Sept. 4 to Sept. 11, according to Interscope, who declined to give a reason for the move. "Curtis" was originally slated for a June 26 release but was pushed back last month.

Two singles from the project have met with little success at radio. "Amusement Park" peaked at No. 36 on Billboard's Hot R&B/Hip-Hop Songs chart and is No. 57 in its ninth week there, while "Straight to the Bank" peaked at No. 30 and has since fallen off the chart.

Another new song, "I Get Money," debuted last week at No. 75. A video for
the track premiered today on Hot97.com.

"Curtis," which is the follow-up to 2005's "The Massacre," features production from Dr. Dre, Eminem and Timbaland, plus guest turns by Eminem, Akon, Justin Timberlake, Mary J. Blige, Robin Thicke and Nicole Scherzinger from the Pussycat Dolls.
