...And we all have the creators of Lost to thank. This is AWESOME news! Here's the scoop from the one and only Michael Ausiello at TVGuide.com.

I can now confirm what I first teased earlier this week: Team Darlton has sealed a deal with ABC to bring us an extra hour of Lost this season.

But there's a twist.

Lost isn't the only ABC hit experiencing an unexpected growth spurt. Sources confirm to me exclusively that Grey's Anatomy will also expand its season by an hour — and it has Lost to thank!

Allow me to explain. With a 14th hour of Lost now a done deal, the show's finale will swell to three hours. But, in what can only be described as an unorthodox scheduling move, the first hour of that finale will air on May 15, and then we have to wait two weeks — until May 29 — to get the last two hours! That's right, no Lost on May 22.

Why?

Apparently, Darlton convinced ABC that the final two hours had to air together. And with the finales of Grey's and Ugly Betty already slated for May 22 at 8 and 9 pm respectively, ABC really had no other choice than to sked Lost's two-hour exit for May 29. That, in turn, created a hole on May 22 at 10 pm — hence the net's decision to tack an extra hour onto the Grey's finale.
