Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

This Current Report on Form 8-K/A (“Amendment No. 1”) amends and supplements the Current Report on Form 8-K filed with the Securities and Exchange Commission by New Source Energy Partners L.P. (the “Partnership”) on February 5, 2014 (the “Initial 8-K”) in connection with the Partnership’s acquisition on January 31, 2014 of working interests in 23 producing wells and related undeveloped leasehold rights in the Southern Dome Field in Oklahoma County, Oklahoma (the “Acquisition”) from CEU Paradigm, LLC, a Delaware limited liability company (“CEU”).

The Partnership disclosed under Item 7.01 of the Initial 8-K that it issued a press release relating to the Acquisition on February 5, 2014, and a copy of this press release was furnished as Exhibit 99.1 to the Initial 8-K. Subsequent to issuing this press release and filing the Initial 8-K, the Partnership discovered an error in the press release that incorrectly referred to CEU as an affiliate of Constellation Energy Partners, an unrelated entity. In order to correct this error, the Partnership issued a corrected press release later on February 5, 2014. This Amendment No. 1 amends and supplements the Initial 8-K to supplement the information furnished under Item 7.01 of the Initial 8-K and to furnish the corrected press release as an exhibit. No other amendments are being made to the Initial 8-K by this Amendment No. 1. This Amendment No. 1 should be read in connection with the Initial 8-K, which provides a more complete description of the Acquisition.

As described above, the Partnership issued a corrected press release relating to the Acquisition on February 5, 2014. A copy of the corrected press release is furnished as Exhibit 99.1 to this Amendment No. 1 and is incorporated herein by reference.

The information furnished pursuant to this Item 7.01, including Exhibit 99.1 to this Amendment No. 1, shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934 and will not be incorporated by reference into any filing under the Securities Act of 1933 unless specifically identified therein as being incorporated therein by reference.
