"Transformers" star Tyrese Gibson has upset patriotic NBA fans after altering the lyrics of the national anthem at Game 5 of the Western Conference finals on Wednesday.
The 30-year-old actor/singer turned up to sing the Star Spangled Banner at the Staples Center arena in L.A.
However, Gibson, who hails from California, took the chance to sing the anthem and cheer his favorite team at the same time.
He replaced the line "our flag was still there" with "our Lakers were still there."
The switcheroo incited more boos than cheers from the audience. And according to different online commentators, Gibson's offense was doubled since he sang the mangled lyrics just two days after Memorial Day.
E! News reports that the actor - who will be seen in the upcoming "Transformers: Revenge of the Fallen" - has yet to comment on the controversy, although he posted a Twitter message, saying he feels "sick" due to his sudden unspecified images and has canceled all schedules for the day.
His faux pas seemed to work, though. L.A. Lakers triumphed over the Denver Nuggets with a 103-94 win.
