Ashlee Simpson and Son Bronx Wentz Play on the Beach in Hawaii

Singer is spotted with her little one during a family vacation

It looks like Jessica Simpson and Eric Johnson aren't the only ones enjoying a little fun in the Hawaiian sun.

While the soon-to-be parents of two were snapped enjoying a stroll in the sand on Wednesday, the pregnant star's sis, Ashlee Simpson, laughed and played on the beach with her 4-year-old boy, Bronx.

Mother and son were all smiles as they spent some quality time together.

The sighting comes just weeks after the two were seen shopping for a Christmas tree amid rumors Ashlee had broken up with her Boardwalk Empire beau, Vincent Piazza.

Whether the split is true or not, it obviously hasn't put a damper on this family vacay!
