Why Is Kate Gosselin Tweeting With Jon's Ex-Girlfriend Hailey Glassman?

Three years after the reality-TV couple split, there appears to be no bad blood between the women

Hailey Glassman may have begun dating Kate Gosselin's ex-husband, Jon, just weeks after the reality-TV couple's very public split in 2009, but three years later there doesn't seem to be any bad blood between the women.

In fact, they're even sharing recipes on Twitter…

"Hey @kateplusmy8 can u share the recipe for the "Monkey Munch." It's so yummy," Hailey, who also broke up with Jon in 2009, tweeted Sunday. "my mom & I never seem to make it as tasty as you did."

Kate, 36, happily obliged. "@hAiLeYgLaSsMaN1 go to the chex website… it should be there. Not my recipe but love it!" the mom of eight tweeted. "Called 'muddy buddies' there! Enjoy! :)"

It was Hailey's father, a New York plastic surgeon, who performed Kate's tummy tuck in 2006. The Gosselins and Glassmans became close family friends after that. Jon, 34, even moved in with Hailey's parents after he and Kate split in 2009.

Despite the fact that he quickly entered into a relationship with Hailey, she insists there was never any animosity between herself and Kate.

Now we have the proof.
