Katherine Heigl Still Wants Back 'Grey's Anatomy': 'I Feel Like I'm Missing The Party'

Katherine Heigl wants you to know one thing: She's really, really sorry that she left "Grey's Anatomy." So sorry, in fact, that she can't even watch the show anymore.

"It just makes me sad ... I feel like I'm missing the party," Heigl told TVLine. "I live about five minutes from the studios, so I have to physically hold myself [back] from just popping in and being like, 'Hey guys -- whatcha doin'?"

Heigl left her role as Dr. Izzie Stevens on "Grey's Anatomy" after five seasons in 2010 to focus on her movie career, and while making the press rounds for her new movie "One For the Money," she mentioned that she would like to return to the ABC medical drama. Now, it's seemingly all the actress can talk about.

"I really, really, really want to see where [Izzie] is," Heigl told E! Online late last week. "I just want to know what happened to her and where she went and what she's doing now." Heigl said she's even reached out about it. "I've told them I want to," she told E!

Days later on "The View," Heigl confirmed that she's approached the writers about a possible return to Seattle Grace. "I always felt that if they wanted me to come back and sort of wrap up that storyline," Heigl told the ladies of "The View," with her adopted daughter Naleigh by her side. "I want them to know that I'm down with it if they want me to, but I completely understand if it doesn't necessarily work."

Although Heigl has yet to be approached by the "Grey's" writers, which TVLine confirms, she's not giving up hope just yet.

"You never know," teased Heigl.

"Grey's Anatomy" will air a special alternate universe episode, titled "If/Then," -- sadly, without Izzie Stevens -- on Thurs., Jan. 26 at 9 p.m. EST on ABC.
