Jennifer Lopez is the queen of all media.

Well, at least music and film.

Lopez's sophomore album, J.Lo, debuted at No. 1 on both the Canadian and U.S. charts yesterday -- selling 22,984 and 272,662 copies respectively -- the same week as her current movie, The Wedding Planner, is at the top of the box office.

It's the first time an artist has had both the No. 1 album and movie at the same time, according to Lopez's record label.

"She is the hottest female movie star out there with the No. 1 film in America. Her album, J.Lo, is No. 1, worldwide," said Sony Music Chairman Tommy Mottola in a press release yesterday.

"And the good news is, this is just the beginning. Need I say more?"

The actress-singer, who is on the cover of the current issue of Rolling Stone, is due in Toronto in two weeks to promote J.Lo., which also went to No.1 in Germany, Switzerland, Spain, Argentina, Greece, Puerto Rico, Central America and Chile.

Her scheduled appearance on The Late Show With David Letterman last night was moved to Tuesday night.
