"I am honored to be a part of the Mardi Gras celebration in New Orleans this year," Spears said in a statement Monday. "It is so important for this amazing city to continue its annual traditions and I am really looking forward to being involved."
The 24-year-old pop star will appear on ABC's "Good Morning America" on Feb. 28 (7 a.m EST), when the morning show reports live from New Orleans. ABC announced that Spears will bring "surprises for a group of very deserving young residents."
The Mardi Gras parade season will run from Feb. 18-28; Fat Tuesday, or Mardi Gras Day, is Feb. 28.
Spears grew up in Kentwood, and has participated in fundraisers for victims of Hurricane Katrina.
The singer also will guest star April 13 on NBC's "Will & Grace."
Last week, photos were published of Spears driving with her 4-month-old son, Sean Preston, sitting on her lap instead of being strapped to a car seat in the back seat. She first blamed pursuits by the paparazzi, but later said it was a "mistake."
On Monday, Transportation Secretary Norman Mineta chided Spears as "irresponsible" for driving with her baby son on her lap and announced a new initiative to improve child car seat safety.
