Move over, Diane Sawyer! Sorry, Barbara Walters. David Letterman is gunning for the number one spot on hard-hitting interviews with celebrities.

The Late Show host had actress Lindsay Lohan as a guest for Wednesday's episode, and didn't let the opportunity to question LiLo about her upcoming rehab stint go by. An uncomfortable Lohan tried to deflect Letterman's questions, but he didn't let her off the hook so easily. Letterman asked:

"Aren't you supposed to be in rehab?"

Lohan retorted: 

"Don't you watch anything that goes on? What are you a tabloid now? May 2!"

Undeterred, Letterman kept the pressure on Lohan about her issues with alcohol, despite the actress remarking they, "didn't discuss this during the pre-interview." Watch a snippet of the interview after the jump! READ MORE

You know, God bless Brian Frons. Even his rival network's late night programming is plugging General Hospital! The sudser's torn asunder medicos Patrick (Jason Thompson) and Robin (Kimberly McCullough), along with that psycho Jezebel, Lisa (Brianna Brown),  were mentioned Tuesday night on Letterman as part of "Top 10 Entries on Barack Obama's Enemies List".  No. 9 was "General Hospital's Patrick for cheating on Robin with Lisa". Check out the clip after the jump!

I did a double take last night watching this ad during the Super Bowl. Leave it to Oprah to bring Jay Leno and David Letterman together in an commerical that plays on the trio's decades of rumored bad blood. Watch the Super Bowl ad after the jump.
