(Updates with official confirmation from HBO.)

HBO has renewed Lena Dunham's Golden Globe-winning comedy, "Girls," for a 12-episode third season, the network said Friday.

The decision is no surprise: Dunham said season three would begin shooting in March during a conversation with Alec Baldwin earlier this week on his WNYC podcast [4], "Here's the Thing."

"I just finished season two," the writer, director and actress said on Monday. "We’re starting at the end of March. I’m so excited."

HBO also said confirmed that the episode order has increased from 10 to 12 -- another bit of information Dunham slipped to Baldwin.

"Well, we’ve been doing 10," she continued. "I think between you, me and McGee, I think we might do 12 next year."

And Dunham's interview makes it sound like she will call HBO home for years to come. She admits it's "not clear" how many seasons of "Girls" she is contractually obligated to continue writing and directing, but says she's locked in as an actor for a total of six years.

"HBO contractually has me I think as an actor for six years but as a writer and director -- I should pay more attention to my deals, but I’m just so excited to have my job," she said. "I just go, ‘Okay, whatever you say.’" 

Dunham, who seems to be in a constant state of excitement, should also be looking forward to the possibility of not just talking to Baldwin -- one of her idols -- but working with him, too.

After she revealed a third season, the "30 Rock" star was quick to add: "I'll be available. I'll come and play your therapist."

"That would be the most fun thing in the world," she responded before later adding: "Working with you is one of my longstanding dreams."
