Kate Gosselin hasn't had sex since January last year

Life & Style can reveal that the last time Kate Gosselin had sex was 15 months ago! According to Stephanie Santoro -- the family's former nanny, who hooked up with Jon after his June 2009 split with Kate -- Jon and Kate hadn't gotten physical since the very beginning of 2009. And she knows because Jon himself told her. "The last time Jon and Kate were intimate was January 2009," Stephanie tells Life & Style.

It's safe to say there's been no one in Kate's life -- or bed -- since. And Kate's the first to admit that won't be changing any time soon. But Kate's off-putting attitude toward men doesn't affect just her -- it could be having a negative impact on her kids too. "It's important for single mothers to date," Millionaire Matchmaker star Patti Stanger tells Life & Style. "Dating makes single moms feel sexy. They go back to their kids recharged and refreshed."

Selfishly, Kate isn't looking to lighten her workload and improve the state of her personal life either. In fact, she was devoting more time than ever to her relentless quest for fame, and the extra time she was spending on the Dancing set wasn't doing much to help win over her co-stars. "She's aggravating people," a show insider told Life & Style before Kate was voted off on Tuesday night. "She makes it sound like she's the only hardworking single mom in the cast. But Niecy Nash and Pam Anderson are single mothers too." The difference? "They're pleasant to be around," says the insider. "Kate's not!"
