Tonight's Lil' Wayne concert at GM Place has been cancelled at the last minute. "The Lil' Wayne show has been cancelled due to circumstances beyond Live Nation's control," the promoter said in a news release on Monday afternoon. The American rapper last performed in Vancouver in January.

Lil' Wayne who dominated rap music at the 2009 Grammys, winning four awards was to share the bill with Young Jeezy, Soulja Boy and Drake.

His Edmonton show, scheduled for Aug. 18, has also reportedly been cancelled. Rumours are flying that rapper got caught up at the Canadian border, although this has not been confirmed.

This isn't the first time Lil' Wayne has had to cancel a concert in Canada. On June 29, 2008, it was announced that his show at Circa in Toronto and a scheduled appearance in Montreal were cancelled "due to unknown circumstances."

Lil' Wayne, whose real name is Dwayne Carter, is currently facing drug charges in Arizona after a search of his tour bus in January 2008 turned up cocaine. His next appearance in court for this matter is slated for October.

The artist's sixth album, Tha Carter III, earned eight Grammy nominations this year — more than any other artist. The Grammy accolades (including winning the award for Best Rap Album) are part of a whirlwind year of career firsts.

He won the MTV Europe Music Awards Artist's Choice Award, and won seven BET Hip-Hop Awards out of twelve nominations in October. Lil Wayne also received three American Music Award nominations and won MTV's Video Music Award for Best Hip-Hop Video.
