One of the biggest games in Atlanta Dream history needed a strong opening act. The team found one in a 10-year-old.

Heiress Harris is 10 years old and the youngest child of Atlanta rapper T.I. and singer Tameka "Tiny" Cottle-Harris. On Thursday she walked onto the floor at State Farm Arena and sang "The Star-Spangled Banner" before the Dream met the Golden State Valkyries in Game 6 of the WNBA Finals. Dressed in a shimmering blue sequin jacket, she handled the high notes with the poise of a seasoned pro in front of a packed home crowd.

The game tipped off in the afternoon, right in the middle of a school day. Few classmates will ever top her reason for missing class.

Social media lights up

Clips of the performance spread quickly online. Alison Mastrangelo, a sports reporter for WSB-TV in Atlanta, shared video of the performance and called the moment incredible. She added that the young singer is wildly talented.

Plenty of fans pointed straight to her mother. Tiny first made her name in the 1990s with the R&B quartet Xscape, the voices behind "Just Kickin' It" and "Understanding." She has also won a Grammy as a songwriter. More than a few people joked that the talent clearly runs in the family.

A Harris family takeover of the Finals

Heiress was not the only member of her household to leave a mark on this series. Her father's summer single "Let 'Em Know" has been blasting over the arena speakers as the soundtrack to the Dream's pregame hype video. T.I. also took the stage alongside Quavo for the halftime show during Game 3.

She is hardly a newcomer to an audience either. Viewers watched her grow up as a toddler on the VH1 reality series "T.I. & Tiny: The Family Hustle." She later joined her dad onstage at his 20th anniversary concert to sing the Rihanna part on "Live Your Life." Most recently she picked up an acting role on NBC's "Grosse Pointe Garden Society."

Then the Dream delivered

Whatever energy she gave the building, the home team used it. Atlanta jumped all over Golden State in the opening quarter, carried a 20-point cushion into halftime and held on for an 80-69 victory.

The win evened the series at three games apiece. It also means the WNBA Finals will go to a seventh game for the first time ever. The deciding game is set for Saturday, Oct. 31, in California, with both franchises chasing their first championship.

Next stop: Tuskegee

Heiress already has her next big crowd lined up. She is scheduled to sing the anthem again on Nov. 7 at Tuskegee University's homecoming, where her father will ride in the parade as grand marshal.
