The singer couldn't stop beaming after Obama's win over Republican John McCain on Tuesday. In fact, she was so inspired, she wore a blue suit and tie in honor of Obama - with stiletto heels that were red, white and blue.
"I've never been so patriotic!" she laughed. "I'm just beyond excited."
Beyonce was supposed to be in Japan on Election Night to promote her upcoming album, "I Am ... Sasha Fierce," but decided to postpone it at the last minute.
"I said, 'What am I doing? I'm completely making a bad decision. I have to go home, I'm gonna kill myself if I'm not home in America,"' she said. "I knew I needed to be here."
After going with hubby Jay-Z, Diddy, Mary J. Blige and others to states like Pennsylvania, Florida, and Ohio just before the election, she watched the returns Tuesday night with family and friends in her home. She was not only inspired by Obama, but McCain's concession as well: "McCain's speech was so classy."
The 27-year-old said the win was particularly important for the inspiration it gave to African-Americans.
"My nephew, who is 4, when we say, 'You can do whatever, you can be whatever,' it's not cliche. You have no doubt that it's not true," she said.
The election even brought Beyonce to tears, though she says it was the good kind: "I fell asleep crying and smiling at the same time," she laughed. I woke up with mascara running and a smile on my face!"
