Shania and more celebs congratulated Bianca Andreescu on her historic win

Long live the Queen of the North!If you somehow missed it, Bianca Andreescu defeated Serena Williams in the U.S. Open final on Saturday, bringing home Canada's first Grand Slam singles title. The 19-year-old now ranks No. 5 in the world in the WTA.When asked what she had to overcome to win, she called out the crowd for not being on her side during the match. "I know you guys wanted Serena to win, so I'm so sorry," she said, a Canadian to the end. The Ontario teen first beat the tennis legend at the Rogers Cup in Toronto when Williams retired due to injury."I've been dreaming of this moment for the longest time," she explained in a press conference. "After I won the Orange Bowl, I really believed that I could be at this stage and since then, I've been visualizing it almost every single day. For it to become a reality, is just so crazy."Other tennis fans were just as excited to celebrate her dream moment, with celebs including Shania Twain, Chrissy Teigen and Simu Liu sending Andreescu love on social media since her victory.
