Enjoying a night out in Sin City, the Simpson sisters and Pete Wentz headed out for the grand opening of the Palms Place Hotel & Spa in Las Vegas on Saturday (May 31).
Upon arrival, Ashlee Simpson and her Fall Out Boy beau posed on the red carpet together before Ashlees big sister Jessica took her turn.
Playing "Power of Love," Wentz said into the microphone, "This is dedicated to my father in law Joe Simpson. I definitely have the power of love for you."
He later dedicated a song to his "baby momma," who was sitting in VIP with her mom drinking water.
