Jessica Simpson and her parents, Tina and Joe, picked up their cars outside of the Viceroy in Santa Monica yesterday. The threesome were just one of many groups of stars celebrating Mother's Day, and they dined at the popular hotel to toast Tina on the special day. Jessica spent her Saturday with other family Ashlee, Bronx Wentz, and Eric Johnson at a photo shoot in LA. It's been a busy few weeks for Jess since she recently made a stop by The Oprah Winfrey Show, was spotted riding bikes with Eric by the beach, and traveled to Denver to sing for First Lady Michelle Obama. Jessica's schedule won't be slowing down any time soon though, since she also has her upcoming wedding to prepare for.
