She is no longer a Gosselin, and her real name isn't even Kate. Therefore Kate Gosselin = Fake.
Kate Gosselin is just a Brand owned and operated by TLC.
It's Katie Kredier DBA: Kate Gosselin.
Of course Jon's real name is Jonathon, but still.
Also, I believe the "kids are depressed because Kate is gone" is just damage control. The kids are already use to Kate being gone for months on end. The real story? Maybe the kids are depressed because Jon is forced to leave the konpound? Kate is away and they want Jon home. The kids are always happy when Jon is home.
The kids didn't look too happy at all when Kate returned to the konpound. Remember, Kate was gone for weeks. No pictures of the kids running to Kate to hug her I see. I bet when she arrived, the kids just looked at her in disgust. "whatchu doin here lady?".
Which explains why the paps only decided to upload pictures of the kids with this new guy. I mean, if Kate is doing this all for the kids, and her kids are her #1 priority, why not hug them and kiss them when she gets home. Instead of hiding in her pad lock room and kicking her kids out to play when some stranger.
