File this one under: Never Would Have Guessed. Ever. US Weekly magazine is reporting that 'America's Next Top Model' judge "Miss J" Alexander has a surprising secret: He has a 7-year-old son named Boris.

"I'm a dad," he announced on 'The Tyra Show' Tuesday.

The former model and self-professed "runway coach extraordinaire" said he and his ex-boyfriend Alex -- whom he dubbed "the Doctor" -- were both sperm donors.

"A French lesbian had asked if we would be sperm donors," he told show host Tyra Banks. "So we thought, 'OK, you want me to do you?' And she was like, 'Ooooh, I'm not that talented.' So I said, 'Okay fine.' So we did a little test tube."
