Jessica Simpson was left lost for words again onstage in California on Friday night when she forgot the lyrics to her song Remember That.

The pop star famously flubbed her Dolly Parton tribute song at the Kennedy Center Honors in Washington, D.C. in 2006 and then twice this year forgot the words to the same song she mangled on Friday.

She tried to play down the gaffe with humor, telling the California audience, "I always forget this," adding "I didn't write it". The singer then joked, "It just comes with the whole Jessica Simpson thing."

She "messed up" the same at a concert back in March, and told fans, "I'm so embarrassed! I'm starting over again because I really want you guys to hear the lyrics the right way."
