The singer-entrepreneur used her Twitter account to deny the allegations Perez Hilton made that she was drunk at last night's Adele concert in Los Angeles.

The 31-year-old singer rightfully denied that she was intoxicated while watching the Los Angeles concert of British singer Adele. The rumor started when celebrity gossip blogger Perez Hilton wrote about Simpson's reaction during the show.

"(Jessica Simpson had) lots of drunken swaying and singing and falling; she had herself a real good time," wrote Hilton, who was also present at the concert and just inches away from Simpson's patron seat. The blogger added that since Simpson seemed to be drunk "she mustn't be pregnant," a rumor that has been recently buzzing around Simpson. The singer, who's engaged to New Orleans Saints NFL player Eric Johnson, retaliated with a post she made in her Twitter account.

"There are rumors that I was 'drunk swaying' at the Adele concert last night," typed Simpson. "That wasn't drunk swaying, that was professional dancing!" adds the singer in the same Twitter post.

In a recent post, singer Adele has admitted that she used to rely on drinking to honestly write her lyrics in the past.
