What could be going on here? Former reality television star Kate Gosselin sent her fans a bizarre message about her ex-husband Jon Gosselin and then quickly deleted it, causing rumors to fly that something might be off between the two.

According to the Daily Mail on Saturday, Kate took to her social media networking account to ask about the whereabouts of her ex-husband, as the two share custody of their eight children.

She reportedly wrote, "I'm in 24 hour protection mode here. Can you find out where Jon DJ's tonight and tomorrow pm literally ASAP?"

Gosselin didn't give an explanation as to why she would her followers and virtual strangers about her ex-husband, or why she was even in "protection mode" either.

There's also speculation that Kate might just be stirring the pot or simply jealous over the fact that Jon has finally found a career while he's also making headlines again.

A source close to the Gosselin family said, "She's always up to no good. Jon tries not to think about that stuff. He concentrates on his kids, his music and his own life."

So far, Jon himself hasn't made any comments about Kate's tweet, either.

The couple separated back in 2010 before finalizing their divorce in 2011. Since then, they've barely been on speaking terms as they have been struggling to co-parent their eight children out of the spotlight together.
