IS FOR ACTING
Before she went Gaga, she was on The Sopranos. She says her greatest moment in high school was playing Miss Adelaide in Guys and Dolls.
IS FOR BREADSTICKS
Born an exhibitionist, little Gaga used the appetizers as batons and danced around restaurant tables as a kid on New York’s Upper West Side.
IS FOR CYNTHIA GERMANOTTA
“She would curl my hair and put her lipstick on herself and then on me,” Gaga says of her childhood with mom Cynthia.
IS FOR DON’T ASK, DON’T TELL
Her true self may be a riddle, but one side she won’t hide? Her fight for gay rights, which she calls “completely genuine.”
IS FOR EATS
Fans who spend hours (and even days) camping out to see her don’t go hungry, because she sends them pizza and doughnuts on line.
IS FOR FRIENDS
Gaga has gigged with DJ Lady Starlight and Semi Precious Weapons (singer Justin Tranter, pictured) since her N.Y.C. days.
IS FOR GREAT DANES
The dogs have been fixtures in many of her videos, including “LoveGame,” “Poker Face,” “Paparazzi,” “Telephone” and “Bad Romance.”
IS FOR HAUS OF GAGA
Her Andy Warhol Factory-esque glam squad (“my heart and soul”) is responsible for many of her outrageous costumes, stage sets and props.
IS FOR INSPIRATION
Sure, she’s an original, but she’s credited David Bowie, Madonna, Whitney Houston and even Kermit the Frog as influences.
IS FOR JOGGING
Gaga edits her songs and listens to demos while jogging on the treadmill. “It’s sort of a really special time for me to work out,” she says.
IS FOR KID SISTER
A little nepotism never hurts: Her younger sister Natalie Germanotta appears in the prison scene of her “Telephone” video with Beyonce.
IS FOR LOVERS
There’s been Luc Carl (now her ex) and Norman Reedus (at least in the “Judas” video), but New York City, she says, is “my husband.”
IS FOR MARISA TOMEI
She’s a huge fan of the Oscar winner and has said she’d like the fellow Italian-American New Yorker to portray her in a film.
IS FOR NAILS
Gaga seldom lets her paws go bare. “Polish is more romantic,” she says of her nails, which have also been adorned with rhinestones and chains.
IS FOR OBSESSION
She admits she’s gaga for … Bruce Springsteen! To create Born This Way, she says, “I took the influence of Bruce on my father in my life.”
IS FOR PONIES
Forget about fans copying her style: Now My Little Pony is rocking her looks. And the star has worn necklaces made from the toys.
IS FOR QUEEN
All hail the British rockers, whose 1984 hit “Radio Gaga” inspired the artist formerly known as Stefani Germanotta’s stage name.
IS FOR REDONE
The Moroccan-born producer is her go-to guy for many of her hit songs. She shouts him out on her debut single, “Just Dance.”
IS FOR SLASHER FILMS
Horror movies keep most folks up at night, but not Gaga. “It’s so embarrassing,” she says. “I actually like to fall sleep to horror movies.”
IS FOR TISCH SCHOOL OF THE ARTS
The aspiring star studied music at New York University’s arts program before leaving to pursue a recording career.
IS FOR UNTOUCHED
Per her father’s request to keep part of her body “slightly normal,” she only tattoos her left side, while the right remains ink-free.
IS FOR VIVA GLAM
Says Gaga of her M.A.C makeup line: “I’m most proud of being [their] spokesperson because all the money goes to the M.A.C AIDS fund.”
IS FOR WHISKEY
“I am on the drunk diet,” says Gaga, whose ex Luc Carl is writing a memoir of the same name. “I like to drink whiskey while I am working.”
IS FOR X-RATED
If not for strategically placed tape on her nipples or a digital blur over her crotch, her performances and videos would be too hot for TV.
IS FOR YOUTUBE
She’s the site’s reigning pop icon, with her content surpassing 1 billion views. “Bad Romance” alone has racked up more than 380 million clicks.
IS FOR ZACHARY
As in her godson Zachary Jackson Levon Furnish-John, best known as the son of her pal Sir Elton and his partner David Furnish.
