Following up Joaquin Phoenix’s bizarre interview with David Letterman last month, Billy Bob Thorton sounded wacked out of his gourd yesterday (April 8) during a radio interview in Canada.

The “Monster’s Ball” actor and his band the Boxmasters did a promotional spot on CBC public radio during which the host, Jian Ghomeshi, had a hard time extracting intelligible answers.

David Letterman tied the knot with longtime girlfriend Regina Lasko and was “not nervous at all” on Thursday, told clerk Lisa Sinto.

5-year-old son Harry was with the couple while filling out their marriage application and “was running around looking at things and being a typical little boy,” Sinton says.

He’s been a longstanding bachelor, though he’s been with the same woman since 1986. And during yesterday’s taping of “The Late Show,” David Letterman announced that he finally got married.

The talk show icon exchanged vows with longtime girlfriend Regina Lasko, with whom he has a 5-year-old son named Harry, in a no-frills ceremony in Montana earlier this month.
