Credit: @Fergie Photo: Pregnant Fergie and Joan Rivers

Everything is weird when it comes to Joan Rivers, but it's kind of funny to see pregnant Fergie give the camera this serious expression while apparently sitting on Joan Rivers’s lap as Joan mimes breastfeeding.

What in the world are they doing?

Fergie tweeted this photo today (April 11), writing, "Taping 4 tmrw's @e_FashionPolice. Breast feeding class w/ @joan_rivers."

So E!'s Fashion Police is now in the breastfeeding business? Maybe the 38-year-old Black Eyed Peas singer is really there to talk about her baby bump style. She recently told Life & Style she's planning to keep her rock 'n' roll style through her pregnancy, and at this point she’s only really compromised by wearing lower heels.

Fergie’s first child with husband Josh Duhamel is due this summer. And it's possible after seeing this pic of his wife with Joan Rivers, he'll be traumatized too much to go for Baby #2.
