Katherine Heigl Feels 'Horrible' For Missing 'Grey's Anatomy' Finale

'I really miss that relationship,' she tells MTV News of onscreen romance with Justin Chambers.

Earlier this year, Katherine Heigl's departure from "Grey's Anatomy" caused quite a stir. The rumor mill was rife with gossip regarding the actress' diva-like demands on set, months before her departure (Heigl's last appearance as Izzy was January 21).

But now that Heigl has officially left the program to focus on being a mom to her adopted daughter, she has gone to great lengths to right any wrongs (i.e. the recent Entertainment Weekly cover story titled "I'm Sorry").

MTV News recently caught up with the actress (while chatting about her upcoming romantic comedy "Killers") and discovered that the 31-year-old has nothing but warm feelings for her onetime castmates. And because Heigl had not yet seen the complicated medical drama's season finale, our own Josh Horowitz attempted — via a "creative interpretation" courtesy of Wikipedia — to summarize the detailed plot and bring the actress up to speed so she could comment.

Midway through Josh's delivery of the details, Heigl interrupted when he mentioned that a main character was pregnant.

"I'm sorry, wait," Heigl said and held up a hand to stop the recap for a moment. "A pregnant who? Meredith is pregnant?" she said, totally surprised. "You've made me feel horrible [for not watching yet].

"I'm going to have to watch this now. I have to see [Alex] call for [Izzy] and her never come. ... I really miss that relationship," Heigl said of her former onscreen romance with Alex (played by Justin Chambers). "Justin Chambers is one of the most amazing men and certainly a spectacular actor. I feel oddly attached to him and the character and my character being together. It just seems what's supposed to be, but you can't have it all."
