Alanis Morissette? I call her "Janus" Morissette.

Singer Alanis Morissette becomes U.S. citizen; keeps Canadian citizenship:

...The singer was among some 4,500 people who took the citizenship oath during a ceremony last week at the Los Angeles Convention Center. But Morissette isn't turning her back on Canada - she's maintaining dual citizenship. "I will never renounce my Canadian citizenship. I consider myself a Canadian-American..."

When it came time for the national anthem [at her "citizenship" ceremony], Morissette said, "I wanted to walk up to one of the officials to ask if I could sing the anthem."

Instead, concertgoers at her Los Angeles show that evening were treated to an impromptu version of the Star Spangled Banner during her set...

Now, contrast that with the article "Morissette to headline Canadians at Expo '05" from just ten days ago:

Crowds will be singing ``O Canada" with Alanis Morissette and getting swept up in the drama of Anne Marie MacDonald's epic stories about the country in an elaborate national pavilion at Expo 2005 in Aichi, Japan.

Morissette will headline Canada's gala concert, revealing her new patriotic fervour. She wrapped herself in the Canadian flag hosting last year's Junos and it seems she does not want to leave the Maple Leaf love-in...

Nothing like playing both sides of the imaginary fence. I note also that the Yahoo report on this that was linked to by Drudge said she was 30 years old. I know better.
