Kate Gosselin Spent Birthday Sans Hubby

Jon Gosselin's cheating rumors haven't stopped yet! US Weekly claims in their newest issue that Jon cheated on Kate on her 34th birthday with his not-so-undercover girl on the side, Deanna Hummel. 

US reports that as Kate munched dessert on a surprise trip to the Ace of Cakes' kitchen, Jon did a lot more than help physically challenged kids brave the slopes in Utah.

Sources say that Jon Gosselin commented that he "should" buy Kate jewelry on her b-day, but never followed through, and spent the "booze-filled weekend" with Deanna, "cuddling up" and possibly getting into more shenanigans than we could imagine. US also quotes a source saying that "I know that the kids [Jon is] hanging out with like a little herbal substance."

If this sounds like it's gotten out of hand, you're totally right. We've gathered some tips to catch him cheating before you're the talk of the town, the office, the apartment complex, or the neighborhood.

What to Do, Plus Things to Consider

*Is he buying new underwear and throwing out the old stuff? This could be a cause for concern, especially if you catch a scent of fruity lube. 

*Check your financial records for unusual and unexplained expenses, or collect receipts lying around the house. Even if you aren't trying to sniff out a cheater, it's sound financial advice. 

*Give him a bear hug when he gets home--and inhale. Let your nose be your guide. Even if he's not cheating, he might be sneaking off for a few drinks with the pals before he gets home.

*Take a look at his computer habits. Is he chatting away late into the night? This could be a cause for concern.
