He may not have won season eight of “American Idol,” but glam superstar Adam Lambert’s sophomore album “Trespassing” had enough steam behind it to claim the top spot on the Canadian album chart this week.

Lambert’s second studio album sold 7,300 copies in its first week, according to Nielsen SoundScan. But it was a significantly lower debut than the one fellow “Idol” alum Carrie Underwood scored two weeks ago when her latest “Blown Away” was released.

Lambert’s strong chart showing tops his 2009 debut “For Your Entertainment,” which went platinum in Canada.

After being knocked out of the top spot last week by Adele, Underwood held steady at No. 2 with her fourth studio album selling 6,400 copies. Adele’s unstoppable “21” added another 6,300 units to its jaw-dropping 1.2 million in sales.

Sultry Norah Jones came in fourth with her latest, “Little Broken Hearts,” with Brit heartthrobs One Direction close behind at No. 5.

This week’s other two new debuts were total flops.

The “Graduation Album” from TV’s “Glee” landed with a thud at No. 6, while comedy rockers Tenacious D probably weren’t smiling with the paltry reception that greeted their latest “Rize of the Fenix” at No. 7.

Familiar names rounded out the top 10, with Jason Mraz’ beach-tinged “Love is a Four Letter Word” in eighth, Johnny Reid’s “Fire It Up” at No. 9, and Jack White’s “Blunderbuss” clocking in at No. 10.

In the U.S., Lambert joined six other “Idol” alumni who have topped the album chart — Underwood, Kelly Clarkson, Ruben Studdard, Clay Aiken, Chris Daughtry and last year’s winner Scotty McCreery.

Adele followed in second place, while Underwood’s “Blown Away” dropped to No. 3.
