Weezer's "Make Believe" rockets to No. 1 In Canada.

Nerd rockers Weezer finally did what no other artist could do for three weeks -- unseat pop-opera crooners Il Divo from the top of the Canadian album charts.

Weezer's brand new studio album "Make Believe," powered by the hit single "Beverly Hills," checked in at No. 1 on sales of 18,100, beating out Il Divo's self-titled disc which fell to No. 2 with sales of 17,300.

It marks the first time that Weezer has debuted at No. 1 in Canada, according to Nielsen SoundScan Canada.

Dave Matthews Band had the second-highest entry of the week at No. 2 with "Stand Up" (15,500) the band's first studio album since 2002's "Busted Stuff."

DMB had better luck south of the border, where "Stand Up" debuted at No. 1 in the U.S. with sales of 465,000, according to Billboard.com.

Back in Canada, Michael Buble's "It's Time" moved from No. 3 to No. 4, Nine Inch Nails' latest disc "With Teeth" fell three spots to No. 5, and Green Day's "American Idiot" occupied the No. 6 position.

50 Cent's "The Massacre" sank from No. 4 to No. 7, while Gwen Stefani's "Love.Angel.Music.Baby" and Jack Johnson's "In Between Dreams" both remained at No. 8 and No. 9, respectively.

"Canadian Idol" runner-up Theresa Sokyrka re-entered the Top 10 at No. 10 with her debut album, "These Old Charms."

Other notable debuts this week included Robert Plant and Strange Sensation's "The Mighty Rearranger" at No. 14, WWE wrestler John Cena's "You Can't See Me" at No. 15, the compilation Z103.5 Hit Mix at No. 17, and The Road Hammers' self-titled debut at No. 21.

In the U.S., Weezer took second place, followed by Mariah Carey's "The Emancipation of Mimi" in third, and 50 Cent in fourth.
