Exhibit 99.1

Unaudited Pro Forma Combined Financial Statements

On May 2, 2011, Lone Star NGL LLC (formerly known as ETP-Regency Midstream Holdings, LLC the “Joint Venture”), a newly formed joint venture owned 70 percent by Energy Transfer Partners, L.P. (“ETP”) and 30 percent by Regency Energy Partners LP (the “Partnership”), completed its acquisition of all of the membership interests in LDH Energy Asset Holdings LLC (“LDH”), a wholly owned subsidiary of Louis Dreyfus Highbridge Energy LLC, for $1,972,000,000 in cash, subject to customary post-closing purchase price adjustments (the “LDH Acquisition”). LDH’s coal assets were transferred out prior to the acquisition and were not purchased by the Joint Venture. The Partnership contributed $591,600,000 in cash to the Joint Venture in exchange for a 30 percent interest. The Partnership funded a portion of this capital contribution with the net proceeds from a private placement of 8,500,001 common units representing limited partner interests of $203,900,000. The remaining portion of the Partnership’s capital contribution to the Joint Venture of $387,700,000 was funded through borrowings under the Partnership’s revolving credit facility.

This unaudited pro forma combined financial information has been prepared to reflect the transactions described above.

The pro forma combined balance sheets reflect the transactions described above and the pro forma adjustments as though the purchase of the 30 percent interest in the Joint Venture occurred on December 31, 2010 and March 31, 2011, respectively, while the pro forma combined statements of operations reflect the transactions described above and the pro forma adjustments as though the purchase of the 30 percent interest in the Joint Venture occurred as of January 1, 2010 for the year ended December 31, 2010, and the three months ended March 31, 2011. The pro forma adjustments were prepared applying the rules established by the Securities and Exchange Commission in Article 11 of Regulation S-X.

The historical financial information included in the column entitled “Partnership” was derived from the audited financial statements included in the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2010 and from the unaudited financial statements included in the Partnership’s Form 10-Q for the three months ended March 31, 2011.

The unaudited pro forma combined financial information is based on assumptions that the Partnership believes are reasonable under the circumstances and are intended for informational purposes only. Actual results may differ from the estimates and assumptions used. The unaudited pro forma combined financial information is not necessarily indicative of the financial results that would have occurred if these transactions had taken place on the dates indicated, nor are they indicative of future consolidated results.

Notes to Unaudited Pro Forma Combined Financial Information

The following notes discuss the columns presented and the entries made to the unaudited pro forma combined financial information.

Partnership

This column represents the historical audited consolidated balance sheet as of December 31, 2010 and related consolidated statement of operations of the Partnership for the periods from May 26, 2010 to December 31, 2010 (“Successor Period”) and from January 1, 2010 to May 25, 2010 (“Predecessor Period”), as reflected in the Partnership’s audited financial statements as reported in its Annual Report on Form 10-K for the year ended December 31, 2010; and the historical unaudited condensed consolidated balance sheet as of March 31, 2011 and related condensed consolidated statement of operations for the three months then ended, as reflected in the Partnership’s unaudited financial statements as reported in its Quarterly Report on Form 10-Q for the three months ended March 31, 2011.

Pro Forma Adjustments

a. Represents the purchase of a 30 percent interest in the Joint Venture for $591,600,000. The Partnership funded a portion of the purchase price with the net proceeds from a private placement of common units of $203,900,000. The remaining portion of the Partnership’s capital contribution to the Joint Venture of $387,700,000 was funded through borrowings under the Partnership’s revolving credit facility.

b. Represents the Partnership’s portion of the Joint Venture’s net income for the year ended December 31, 2010 and the three months ended March 31, 2011, adjusted for the portion of LDH not acquired by the Joint Venture as well as the additional depreciation and amortization expense resulting from the purchase price allocation. The Joint Venture acquired substantially all of the assets of LDH; therefore the Partnership included the audited financial statements of LDH for the three years ended December 31, 2010 in Exhibit 99.2. A reconciliation from LDH’s audited net income for the year ended December 31, 2010 and the unaudited net income for the three months ended March 31, 2011 to the pro forma net income associated with the assets acquired by the Joint Venture is presented below.

		Year Ended December 31, 2010			Three Months Ended March 31, 2011
		(in thousands)
LDH’s net income		$	90,586		$	26,225
Add (Deduct):	Net loss associated with the coal assets that were not acquired by the Joint Venture		500			100
	Additional depreciation and amortization expense as a result of purchase price allocation*		(37,882	)		(8,846	)
Pro forma net income associated with the assets that were acquired by the Joint Venture		$	53,204		$	17,479
The Partnership’s 30 percent equity income pro forma adjustment		$	15,961		$	5,244

* Management of the Joint Venture engaged a third party valuation expert to undertake a detailed purchase price allocation and valuation study. The estimated additional depreciation and amortization expense is calculated based on the preliminary valuation result.

c. Represents the incremental interest expense incurred on the borrowings under the Partnership’s revolving credit facility that were used to fund a portion of the acquisition of the 30 percent interest in the Joint Venture. The Partnership utilized the weighted average rates of its revolving credit facility of 3.87 and 3.10 percent for the year ended December 31, 2010 and the three months ended March 31, 2011, respectively.

d. Represents the issuance of 8,500,001 common units.
