Jessica Simpson, 40, looks better than ever! The “Sweetest Sin” singer rocked a dark pair of skinny jeans and platform shoes as she posed on a bike in photo posted to Instagram on Saturday, Oct. 10. “Trying my hardest to feel peaceful riding my 7yr old sons bike. You can’t see them, but you know I’ve got 5-inch platforms on to reach the pavement for grounding,” she joked, referencing her son Ace, 7, with husband Eric Johnson, 41.
