Jessica Simpson is a business genius, tweeting a tease to her fans of herself back in a swimsuit just five months after  having her second baby – and guess what she is modeling? A plunging white swimsuit from her JS collection.

The photo was caption, “Guess which mama I get to play dress up with today? #bts”

“The shot is deliberately blurry, so everyone will want to see the final pictures,” a friend tells NAUGHTY BUT NICE ROB. “She is showcasing her slender new frame and at the same time selling her line. It really is genius. She knows everyone is consumed with her weight, this is not a press opportunity that Jess is going to let slip by.”
