30 Rock's Tina Fey graces the March issue of Vogue and talks a little about how she sent e-mails to Vogue subscribers, and how her infamous "Mom Jeans" line came to light.

Vogue subscribers recently got a very interesting e-mail from Fey herself exclaiming: "My Vogue Cover". There Fey describes her experience working with Vogue, with of course a little humour added into the mix. Fey mentions "If you've always wondered what it would be like if the talented people of Prada, Gucci, Dolce&Gabanna, and Vogue gave your 40-year-old sister-in-law a makeover, then this is the issue for you".

Fey also compares working with Vogue to once in a life time opportunities such as watching Mount St. Helens volcano erupt or seeing Halley's comet.  Meanwhile Tina Fey's famous one liner "Mom Jeans" became an instant classic back on Saturday Night Live, but now Tina is recalling to Vogue how she came up with the idea.

"The idea for Mom Jeans first came up after I had a fire in my apartment and had to buy a pair of emergency jeans for work one day, it was right before the low-rise thing kicked in officially, and I inadvertently bought these jeans, and they had this enormous rise," Fey says. "And I was going around the office complaining about them all night, joking about it, and Maya Rudolph (SNL co-star) and I started singing a little Mom Jeans song. We just goofed around, and I wrote that up very quickly".

Fey also talks about her new interest in fashion, dressing for the red carpet and of course 30 Rock.

The March 2010 issue of Vogue goes on sale Tuesday.
