The new mom, who welcomed daughter Maxwell Drew Johnson on May 1, is rooting for crooner Phillip Phillips to win Wednesday night.
"Crossing my fingers for hot stuff Phillip Phillips!!" she Tweeted Wednesday afternoon.
Phillips, 21, performed three songs alongside another Jessica – 16-year-old Sanchez – Tuesday on the show's final night of competition.
And Simpson, it seems, is ready for some new music (lullabies excluded, of course).
"I want his record NOW!!!" she continued in her Tweet.
