He’s always up to something, and last night (February 29) Neil Patrick Harris paid a visit to “The Late Show with David Letterman.”

The “Doogie Houser” hunk chatted with Letterman about taking his 17-month-old twins on vacation with him to Las Vegas.

But probably the highlight of the interview is when NPH teased that he’d finally, after seven seasons, reveal who the mom is on his television gig “How I Met Your Mother.”

Building up the hype a bit, Harris told Letterman, “The mother on the CBS show ‘How I Met Your Mother’- Oprah Winfrey.”
