North West, daughter of American rapper Kanye West, performed her own song on stage for the first time, local media reported.
The 12-year-old girl performed in front of 42,000 people at her father's concert in Mexico. She sang about her recent finger piercing.
Previously, Kardashian and West's daughter starred in an advertisement for her mother's brand.
A day earlier, Kim Kardashian posed in a silver corset dress with a plunging neckline from Mugler's vintage collection from 1986. The model wore statement earrings and wore her hair in a high ponytail, with brown eyeshadow.
The businesswoman was photographed in front of a Christmas tree with her children - 12-year-old North, 10-year-old Saint, 7-year-old Chicago and 6-year-old Psalm.
