Hailey: Jon Gosselin Is My "First Love"

Hailey Glassman calls beau Jon Gosselin her "first love" in her first interview since hooking up with the father of eight.

Glassman also reveals she began dating Gosselin in May -- one month before he and Kate announced their separation on Jon & Kate Plus 8 in June. Glassman says Jon and Kate were separated for "months" before then, and she had nothing to do with their split.

Kate who? See all the women Jon has dated since their split.

"He was living in my house, the person I joked around with. He was sad and bored, I was home and bored," says Glassman, the daughter of the surgeon who performed Kate's free tummy tuck. (Kate also stayed at the Glassman residence after going under the knife.) "Jon and Kate have moved on with their lives -- it's only the viewers who haven't moved on," adds the 22-year-old, who debuted her relationship with Jon on a vacation to the South of France in July.

Glassman swears she's not dating Jon to get famous. "I'm not some famewhore. I've been in hiding for three months," she says, adding that the attention she's received since hooking up with Jon has "been horrible." "Do I choose my life or do I choose Jon?" she says. "I stay in my house with my parents where I feel safe. Take my 15 minutes, you can have it back. Please take it back!" Glassman says she "wasn't worried" about her beau going to the Hamptons with former tabloid reporter Kate Major last month.

"I know what Jon tells me and I know him, but she's cuckoo, cuckoo, you know?" she says. Last month, Gosselin told Us his "heart is always with Hailey." Still, Us Weekly has reported he's been acting like a single man, and even had an overnighter with 22-year-old single mother Stephanie Santoro, one of his babysitters. Kate and Jon got into such a heated argument over Santoro at their $1.1 million Pennsylvania home Thursday night, police ordered her to leave the property. "Kate tried to 'cry it up' with the cops and it didn't work and they said, 'You have to leave,'" Jon said today. "I guess she didn't agree with my babysitting."
