Was Jessica Simpson doing a little drunken dancing during a concert earlier this week by British singer Adele?

During Monday’s show at the Greek Theatre in Los Angeles, Simpson was spotted grooving to the music in a manner that some described as “drunk swaying.” Simpson defended herself the next day, tweeting, ”There are rumors that I was ‘drunk swaying’ at the Adele concert last night. That wasn’t drunk swaying, that was professional dancing!”

Christina Aguilera and ‘Glee‘ star Dianna Agron were also spotted at the show, but the kind of dancing they might have been doing — drunk, professional or otherwise — is not known.
