Donna M. Carter appeals the district court’s 1 order affirming the denial of disability insurance benefits. Upon careful review of the record, see Medhaug v. Astrue, 578 F.3d 805, 813 (8th Cir. 2009) (standard of review), we find that the administrative law judge’s (ALJ’s) credibility determination is entitled to deference because it was based on several valid reasons, see Finch v. Astrue, 547 F.3d 933, 935-36 (8th Cir. 2008); and that it was *968 proper for the ALJ to decline to give weight to the vague, conclusory, and unsupported opinions of treating physician Charles Pigneri on Carter’s residual functional capacity, see Brown v. Astrue, 611 F.3d 941, 952 (8th Cir. 2010). We reject Carter’s assertion that the new evidence she offered in the district court justifies remand, see Jones v.
