Bayern Munich became women's Bundesliga champions for the eighth time, and fourth in a row, after a 3-2 win at Union Berlin on Wednesday.
The victory took Bayern an unassailable 15 points clear of second-placed Wolfsburg, who could only manage a 0-0 draw Werder Bremen.
With the scores level at 2–2 late on, Bayern looked set to drop points for only the second time in the league this season, but substitute Giulia Gwinn struck in the 84th minute to snatch victory and the title for the visitors.
Edna Imade and Barbara Dunst also got on the scoresheet for Bayern, while Union's Sophie Weidauer and Lia Kamber scored for the hosts in front of a crowd of 13 220 in the German capital.
Next up for Bayern is their Champions League semifinal first leg against Spanish giants Barcelona in Munich on Saturday.
"This is absolutely incredible," Dunst told reporters, before adding: "We have another big match coming up in the next few days, so we're taking it easy for now. We'll save it for later.
Gwinn said the side would celebrate with some "good music – and maybe a shandy or two."
The victory, which came three days after the men's team won the Bundesliga with four games remaining, demonstrated Bayern's dominance of the German game.
Both Bayern's men's and women's sides remain on track for a treble, a feat which has never been achieved in European football.
Bayern's men go to holders Paris Saint-Germain in the first leg of their Champions League semifinal next week.
Bayern's women face rivals Wolfsburg in the German Cup final. The men play at Bayer Leverkusen in the semifinals later on Wednesday.
