"I sat here a year ago and I watched my big girl leave – I'm back on this porch and I am now officially an empty nester," Shields, 59, began, as she referred to her two daughters being enrolled at the same school.

"They're together at least, but it's really not – it's not easy for the moms," she said in an Instagram video. "I mean, it's just so weird. It's so weird that she's not here."

Throughout the video, the "Pretty Baby" star wiped tears from her eyes and recalled the difficult moment she departed from her daughter.

"It was really hard and then she started crying… I really started crying and then I cried a good portion of the ride home."

"I'm an empty nester. Wow," she added, as she fought back tears.

"To this day I believe that I fell in love with Chris the day we met, in 1999, but I would never tell him that!" she wrote in her 2005 memoir. "I had just gotten an American bulldog, Darla, and I brought her to meet friends of mine in the gym on the Warner Bros. lot. While there, the dog wandered off, and Chris brought her back. He was writing for a show filmed on the lot and loved dogs. We chatted and he made me laugh."

The couple got married in 2001. "The Blue Lagoon" star gave birth to Rowan in 2003 and Grier in 2006.
