The Bravo Upfronts are happening this week in New York, and The Real Housewives of Atlanta are northbound for the event. But one Hotlanta housewife is headed to NYC in tears... why is Kim Zolciak having a cry fest?

Because she's a doting mama, that's why! The mother of four took to Twitter to vent her emotions over saying goodbye to her adorable two sons.

So sad leaving my babies 2day heading to the big apple ... only my 2nd time leaving Kash!!! Crying on the way to the airport!," Kim wrote. Aww.

If Kim gets this emotional about leaving her little guys for just a few days to fly up the coast, it's no wonder she wasn't ready to go to a whole other country for an entire week with Kenya Moore and company.

Do you think Kim is too attached to her tiny men, or is she just being a normal mom?
