I want to know the answer to the following question:
Which two stars did Beyoncé help with their Haiti Earthquake organization?
All the background I'm provided with is that "In April 2011, Beyoncé joined forces with US First Lady Michelle Obama and the National Association of Broadcasters Education Foundation, to help boost the latter's campaign against child obesity by reworking her single "Get Me Bodied".". Is that enough to answer the question?
Answer: no
