After 11 years, Heather Morris has still got it. The 34-year-old Glee star took to social media to dress like Britney Spears and dance to her song, “Slave 4 U” which she first reenacted on the hit show over a decade ago. In the video, Heather, who played Brittany, looked amazing in a white button-down shirt that she tied in a knot to be super cropped.
