Lady Gaga made good on her promise to appear on Howard Stern's morning satellite radio show on SiriusXM. Her manager made a bet that Gaga would appear and that she did, fresh off her trip from Down Under. Of course, Stern told her that she looked hot, since she was pants-free, with her stating, "I don't like wearing pants." That we already know.

But Stern, known for posing the hard questions, digging deep and asking celebrities about things that make them uncomfortable, did not lob softballs at Gaga and she fielded them like the media savvy pro that she is! It was a brilliant slab of radio gold, as Gaga and Stern handled each other brilliantly. There was rapport and humor, and plenty of revelations about the last time she had sex, her past cocaine use and her loss of virginity.

Gaga talked about her upbringing in NYC, playing Atari and standing on the piano and performing like Jerry Lee Lewis as a kid. She also performed a few songs, including 'Hair' and 'The Edge of Glory.'

About her parents' acceptance of the Gaga persona, which includes high heels at all times: Her parents also call her Gaga now, too. She even wore a sweater (her dad's), jeans and sneakers after his heart surgery. When her dad awoke, after surgery, Gaga revealed that he said, "You look like hell. Go home, put a wig on, some make up and come back when you look like yourself."

About her "boyfriend" Luc Carl: "What boyfriend? It's hard to find a boyfriend who doesn't mind a good tuck." Stern asked how she would find someone who she could trust and who would "get" her since she is so famous and so creative. Gaga responded, "I like guys with long hair who know a lot about rock 'n' roll. That's it … It's just that my first love is music." She also said she got laid last night, but didn't say by whom. "Sorry, I sound like a whore, I guess I walked right into that one!" She said that "Luc is going to be doing a show on Sirius. He is my best friend."

About her success:
She said she doesn't have any clue how much money she has made, saying, "I don't give a f--- about money at all. I just came from my apartment from Brooklyn, which is smaller than this studio. I bought my dad a Rolls Royce and paid for his heart surgery." She also said that the first Monster Ball in America, which was a theater tour, lead to $3 million worth of debt. She told her manager to keep her on the road to make up for the debt. She cares most about making music; the money comes second.

About her father's reaction to her shows was not negative, but more like "Hell f---ing no, I can't believe you are doing that!":
Gaga actually said all of that, telling listeners how her father came to her early burlesque shows, saying, "I was dancing to Judas Priest in a thong on stage, and he was having a freaking heart attack and I was like 'Daddy, it's performance art.'" But she said her dad sees himself in her, as he used to go see Bruce Springsteen and have sex with girls under the boardwalk in New Jersey. "I think he saw himself in me and got scared."

About her love of classic rock, which came from a tradition in the Germanotta household: "Every single night, it was a ritual before and after dinner, he'd play Pink Floyd, Led Zeppelin, Bruce Springsteen, Billy Joel."

About her humble beginnings and failed IDJ record deal: She said, "It was about 'How do you make your daddy proud? How do you make an honest woman of yourself?' I was leaving a legacy for our family. My parents didn't come from money. I didn't come from money. They both were the first to go to college."

About her drug use: She said she doesn't get high anymore. She hinted that she still smokes weed, suggesting it's not really a hard drug, saying, "I don't do it very often. I am honest about it. I don't like or respect artists who lie about what they do recreationally. It builds a separation with your honesty with your fans." She said she doesn't remember the last time she did coke, but at one time, she was "for sure addicted." She said Papa Germanotta got her off the white stuff, and "kicked my ass. Not really. He just called me out." If you know anything about old fashioned Italian fathers … This should not be surprising. She also said the drugs were like a friend and she preferred to use alone in her apartment while she wrote music. "I regret every line I ever did, so to any of the little sweethearts listening, don't touch it, it's the devil!"

About Britney Spears recording the Gaga-penned 'Quicksand' and recording but not using the Gaga-penned 'Telephone': "Freaking Britney Spears sang my record? I was doing backflips and ordering drinks" was her overjoyed response to Brit Brit recording her songs, even if she nixed 'Telephone,' and we all know where that ended up!

About losing her virginity: She was 17, he was older and it was not Luc Carl. "As a woman, you don't even enjoy it until your mid-20s. When you are 17, you don't know how to operate what's going on down there so don't even try. I think kids have sex way too young."

About experimenting with women: "That was later. I was in college, which was brief."
