According to multiple overseas sources, Lil Wayne must cancel upcoming shows in Europe and the United Kingdom after he was denied a visa due to a recent firearms conviction.

While currently touring the U.S. on his I Am Still Music trek, Weezy was set to embark overseas for a smattering of dates and summer festivals to coincide with the release of his ninth studio album, 'Tha Carter IV,' in May.

Wayne didn't have many set dates before receiving the bad visa news, though. He had confirmed an appearance for the Live at the Marquee festival in Cork with tickets to go on sale today (April 1). That show has been canceled before fans could even buy passes to attend.

UK publication Stereoboard has cited specific documents that show Wayne's visa was denied because of his 2007 weapons arrest and subsequent eight-month prison sentence. They also cite run-ins with police finding marijuana, cocaine and MDMA on his tour bus in 2008, and another weed bust on the Texas border in 2009. Wayne was never convicted of the charges from these stops, so grounds to suspend a visa seem tenuous at best.

While he works these issues out, Wayne is certainly keeping plenty busy. He continues to tour with Nicki Minaj, Young Money labelmates, Rick Ross and Travis Barker, while recently revealing that he is so busy that he never even had time to listen to records by his biggest earners Drake and Minaj.
