Erëleta Memeti scored the only goal of the game for Kosovo.
Hegerberg last played for Norway at Euro 2017 — where the much-fancied Norwegians exited at the group stage — before announcing she would no longer represent her country.
The 2018 Ballon d’Or Feminin winner said her decision came down to frustrations with the way women’s football was treated within the country and led to her missing the 2019 World Cup in France.
Hegerberg’s return is certainly timely for Norway, who will be hoping the presence of their star forward, widely considered one of the most clinical finishers in the women’s game, can lead them to glory at this summer’s European Championships.
The 26-year-old now boasts an impressive 41 goals in 67 appearances for the national team, as Norway sits top of Group F after six matches of World Cup qualifying.
