The first Democratic debate kicked off on Tuesday night, finally bringing the top presidential candidates face to face. Hillary Clinton and Bernie Sanders were in attendance, along with other hopefuls like Martin O'Malley, Jim Webb, and Lincoln Chafee. Before the event, CNN took to Twitter and Facebook [1] and asked celebrities to send in the questions they wanted the candidates to address. Stars like Katy Perry [2], Demi Lovato [3], and Ashton Kutcher [4] all chimed in, and we have to say their questions were on point. Read on to see what they said, then check out all of our 2016 election coverage [5].

Demi Lovato — Health Care

"What's the biggest issue with our health care system when it comes to mental health care, and what specifically will you do to fix it?"

Katy Perry — Planned Parenthood

"With the GOP crusade to defund Planned Parenthood momentarily deflated, how do you intend to consistently protect American women seeking the legal, affordable health care that they so desperately require?"

Ashton Kutcher — Innovation

"During your presidency, you will be faced with a robotic revolution — for example, driverless cars and semitrucks — as machines take skilled and unskilled jobs from Americans. This will further hollow out the middle class and divide society. What do you propose we do as a nation to bridge the gap without stifling innovation? What will you do as president to maintain a country where everyone has upward mobility?"

Elton John — AIDS

"In spite of great progress, HIV/AIDS is actually dramatically on the rise in the U.S. South. What would you do as president to help stop this epidemic, particularly among minority communities?"

Shonda Rhimes — National Unity

"There is so much divisiveness is our government today. Achieving anything of substance seems impossible because compromise seems impossible. What do you think needs to be done to unite Congress so that they are working more for the good of all of the American people as a whole and less for the good of the partisan interests that seem to have currently halted any hope of legislative change or progress?"

Julianna Margulies — Gun Control

"Next year, the citizens in Nevada will vote on an initiative to require the same Brady background checks that are conducted at licensed gun dealers to be conducted for sales made at gun shows and online. Do you support that initiative and, as president would you seek to make it federal law?"

Margaret Cho — Adoption Rights

"How do you allow LGBT couples who are now able to be married under the law full adoption rights in every state? How do we get equal rights to family?"
