Blue Ivy Carter, daughter of Beyonce and Jay-Z, is a huge LeBron James fan and had the sweetest encounter with the NBA star at the Staples Centre on Sunday night.

After Los Angeles Lakers defeated the Clippers in a thrilling match, Blue Ivy Carter, who watched the match with her father Jay-Z, approached LeBron James for an autographed basketball, reports People.

In footage shared by ESPN, the eight-year-old was seen fangirling over James, as she joined her father to congratulate the athlete after his team's victory. Blue Ivy briefly turns away while James and Jay-Z shake hands, and then gives a huge smile to the player when it's her turn to meet her star.

Though Blue Ivy was feeling shy and finding it difficult to muster words, her father was by her side encouraging her to speak. "If you want it, you gotta tell him. You almost got it out. Yeah, just do it," the 50-year-old rapper can be heard telling his daughter.

The young girl sweetly asked the NBA star for the momento, to which he promised that she would have it by the end of her school on Monday.
