We've talked a lot about the "unforgettable kiss" coming our way on Grey's Anatomy this month - but it turns out that's not the only kiss of significance. TV Guide's Michael Ausiello has the scoop on what we can expect.

Follow the jump for some juicy Grey's Anatomy gossip ...

Question: So much for the suspense surrounding the big Grey's Anatomy kiss. The new issue of TV Guide comes out and says it's Hahn and Callie! WTF?

Ausiello: Au contraire. The TV Guide article actually says Hahn and Callie smack lips this Thursday (in "Losing My Mind.") The "major" kiss Shonda was referring to takes place next week in the season finale â€" and it may or may not pertain to a second, more passionate Hahn/Callie buss. This much I can confirm for you: The May 22 Grey's Anatomy finale features several kisses, all of which I'd characterize as significant. But only one is so good that, to quote Shonda Rhimes, it will make you "lean into your televisions."

Question: Any hints on the Grey's Anatomy finale â€" especially Alex and Izzie?

Ausiello: It's about damn time. That's your hint.

Will Alex and Izzie rekindle the Season 2 magic?
