Late night will meet morning again when David Letterman drops in next week on "Live with Regis and Kelly."

"Live" officials say the CBS "Late Show" host will join Regis Philbin and Kelly Ripa (RIH'-puh) on April 30. That'll be his first visit since Philbin returned to the air after heart surgery in April 2007.

During that appearance, the two compared scars and swapped stories about their bypass operations.

Other stars lined up for "Live" guest shots include Robert Downey Jr. on April 29, with Betty White, Gwyneth Paltrow, Tom Selleck and Russell Crowe appearing the following week.

"Live" is syndicated and airs on weekday mornings.
