Poor Kate Gosselin is NEVER going to win the mother of the year award.
Especially if she doesn't stop screaming at her kids in public.
Radar Online is reporting a fellow concert-goer in Fairfax, Virginia, got all the dirt on Kate's latest eye-opening behavior regarding Cara and Mady:
"We were at the Demi Lovato concert on Sunday night and had just entered the building and were browsing the merchandise table," says the insider.
"I turned and saw a girl who looked familiar but turned away and didn’t think much of it. Next thing you know we heard someone yelling, ‘You both need to come back here now!"
"'Get over here and stay together! Where are you guys going?!' I turned around and lo and behold, it was Kate Gosselin b--ching out the twins."
"The girls seemed embarrassed and their faces were pleading, ‘Please don’t know my mother.’ They looked deflated. Myself and two friends were shocked and appalled."
Not only was Kate yelling at her kids, the source also reports she was holding hands with her bodyguard and rumored boyfriend Steve Neild.
"They are most definitely a couple and were NOT trying to hide it."
Well at least Kate had a nice time. She got to combine two of her favorite activities: yelling at her kids and keeping her 15 minutes of fame going as long as possible.
