What the hell is up with Jessica Simpson these days?

The mother of two looked out of sorts when she did an interview with Extra at the 2015 Teen Vogue Fashion University. The fashionista was supposedly playing dean for a day at the red-carpet event -- but mostly we thought she was acting afool.

From the odd answers to the flailing about, Jessica was acting seriously bizarre at the event. We are almost not surprised to see this -- her behavior has been pretty erratic lately. Last month, Simpson posted some racy, 50 Shades of Grey style Instagram pics -- and raised more than a few eyebrows. We've heard reports of the singer-turned-fashion mogul stumbling out of restaurants.

When the show asked if she was recording music, the blonde gave a heck of a loopy answer, "Right now, I'm starting a record, and I'm getting into a lot of other fun things. I have a recording studio in my house so I can be around my babies as well and they might try and sing over me. They won't be my background vocalists, they'll be like 'ahhh.'"

Uhhh ... What?!

But for reals -- how did her publicist let her do this interview?!
