The singer-and-actress attended the Latino Inaugural Gala in Washington, D.C. and admitted Obama was the only person she was interested in meeting.


She said: “He is the biggest star here, even though it's chock-full of celebrities. The night he won the election, you could feel it in the air. I was watching him with tears in my eyes, thinking, 'Yes. Something is different. Something is happening.' We're very excited.”


Other stars who attended the event included actress Rosario Dawson and singer Shakira, who was also delighted to meet the politician.
