“I have an official Facebook page. I’m not on Twitter, Instagram. I have a couple of reasons. One, I don’t want any more guilt coming from my phone or computer. I have the hardest time answering emails, anyway, so the last thing I want to feel is indebted to my phone or computer. So it’s time,” Jennifer shared to People.

She added, “And the other is, what would I Instagram that people would want to see. There is nothing I would put out that people would want to see. It’s probably best to stay away. They don’t want to see me and my mom friends after kindergarten drop-off.”
