Aguilera sang "Ave Maria" during the emotional performance with an orchestra. Other performers at the event included Beyonce and Alicia Keys.
"Thank you, Christina, that was beautiful. And in Italian, as well," Jimmy Kimmel, the emcee for the event, quipped. The singer blew a kiss to Kobe's family as she stepped offstage.
Staples Center, the location of the memorial, is affectionately known as "the house that Kobe built," as it's where the basketball legend spent most of his 20-year NBA career playing for the Los Angeles Lakers.
The date of the memorial itself, 2/24/20, also holds special significance in that it represents Gianna and Kobe’s jersey numbers, with 20 representing both the amount of years he spent as a Laker and how long he and wife Vanessa were together.
The public memorial follows the private funeral for Kobe and Gianna that was held at Pacific View Memorial Park in Corona Del Mar, California, on Feb. 7.
