Sheila Lewis appeals the district court’s 1 adverse grant of summary judgment in her employment discrimination action. We deny her motion to supplement the appendix with evidence that was never submitted to the district court. See Allen v. U.S. Air Force, 608 F.3d 423, 433-34 (8th Cir.), cert. denied, - U.S. -, 131 S.Ct. 830, 178 L.Ed.2d 565 (2010). After careful de novo review, see Johnson v. Blaukat, 453 F.3d 1108, 1112 (8th Cir. 2006), we agree that summary judgment was proper for the reasons stated by the district court. Accordingly, we affirm the judgment. See 8th Cir. R. 47B.
