A major inspiration for the pop star? Beyonce. Adele stepped out to support the "Run the World (Girls)" singer at London concert in June 2011. "I had a full-blown anxiety attack [before meeting Beyonce]," Adele told Rolling Stone this year. "Then she popped in looking gorgeous and said, 'You're amazing! When I listen to you I feel like I'm listening to God.' Can you believe she said that? Later I went out on the balcony crying hysterically, and I said, 'What would Sasha Fierce do?'"
