I want to know the answer to the following question:
Where did she announce her pregnancy?
All the background I'm provided with is that "In August, the couple attended the 2011 MTV Video Music Awards, at which Beyoncé performed "Love on Top" and started the performance saying "Tonight I want you to stand up on your feet, I want you to feel the love that's growing inside of me".". Is that enough to answer the question?
Answer: yes
