Unlucky in love Liz Lemon is finally getting married.

A mock save-the-date announcement for the fictional 30 Rock character was released by NBC today using one of her famous catch-phrases, 'What the what?!'

Fans of the hit show might have reasonably assumed that Lemon, the harried TV producer played by Tina Fey, would ride out the series' seventh and final season as a perennial bachelorette.

Wedding bells: Tina Fey's character Liz Lemon will marry Criss Chross, played by guest star James Marsden, in 30 Rock later this month

But Fey, who is also the creator and producer of the NBC comedy, clearly thought otherwise.

In the 30 Rock episode airing Nov. 29, Lemon will wed.

Who's the lucky guy? He's Liz's latest fella, Criss Chross (played by guest star James Marsden), a Peter Pan-ish would-be entrepreneur who hatches ventures such as an organic gourmet hot-dog truck.

On Thursday, NBC made the grand announcement that Ms. Elizabeth Miervaldis Lemon, 42, would be presenting herself to be married to Mr. Crisstopher Rick Chross - 'But not in a creepy way that perpetuates the idea that brides are virgins and women are property.'

The invitation also specifies that guests (i.e., you viewers) should plan to 'bring your own snacks.'

No preview of the episode has been made available.

Save the date! NBC issued this mock save-the-date announcement on Thursday

The series, which airs Thursdays at 8 p.m. EST, will conclude early next year.

30 Rock is the saga of Lemon, the overextended producer of a fictitious comedy show loosely inspired by 'Saturday Night Live' (where Fey toiled for nine seasons as cast member and writer). Liz is surrounded by kookie comrades like company boss Jack Donaghy (Alec Baldwin) and Tracy Jordan (Tracy Morgan), her boisterously unhinged star.

A recurring theme of '30 Rock' has been Lemon's comicaly flawed love life. Short-lived boyfriends have included quirky airline pilot Carol Burnett (played by Matt Damon), immature businessman Dennis Duffy (Dean Winters) and dimwitted pediatrician Dr. Drew Baird (Jon Hamm).

But clearly there was something special about Criss, who first arrived on the scene last season.

Even before meeting him, Donaghy was disapproving: 'Lemon, I have said Good God to you before,' he huffed, 'but I don't think I've ever MEANT it until now: Good God!!!'

But Criss is different, Liz insisted: 'I'm more relaxed around him. My jaws stopped popping. And for once I'm not overthinking everything.'

Jack wasn't convinced. He noted that Criss is a puppy-dog-eager dork who carries a Sunglass Hut credit card and owns a ukulele plastered with an Obama sticker.

Is this a match made in heaven? The wedding invitation says, 'Whatever. It's no big whoop.' But the episode is sure to be a very big whoop.
