*755 Wellington Roeli Gonzalez-Cisneros appeals the sentence imposed following his guilty plea to illegal reentry. He argues for the first time on appeal that he is entitled to resentencing because he was sentenced under the mandatory Guideline regime held unconstitutional in United States v. Booker, — U.S. -, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005). We review this argument for plain error only. United States v. Martinez-Lugo, 411 F.3d 597, 600-01 (5th Cir. 2005).

Our review of the record does not reveal that the district court’s error affected the outcome of the sentencing proceedings. See United States v. Valenzuela-Quevedo, 407 F.3d 728, 732-33 (5th Cir. 2005). Gonzalez has therefore failed to establish that the error affected his substantial rights, and he consequently cannot meet the plain error standard of review. Id. Given that Gonzalez is not entitled to resentencing, we pretermit discussion of the validity of his appeal waiver.

AFFIRMED.
