British vocal sensation Adele has enjoyed a successful career around the globe and has even inspired tennis pro Serena Williams to the point where she always sings her tracks at karaoke parties.

During an interview on 'Late Night with David Letterman', Williams explained that now that Wimbledon and the Olympics have finished she can let her hair down and can't wait to perform some Adele songs with her friends:

"I was just talking to my physio today about how the first thing I do when I get to New York is I'm going to karaoke."

"I call it the Adele syndrome, not that I have an Adele voice," she joked. "My voice is so terrible."

The 'Rolling In The Deep' superstar is currently pregnant with her first child and her boyfriend, Simon Konecki, recently revealed that the baby will be born "so soon" although he didn't confirm Adele's due date.
