Kobe Bryant's widow, Vanessa Bryant, is not ready to be an empty nester. The single mom-of-four cried while dropping off her eldest daughter, Natalia Bryant, at the University of Southern California.

The 39-year-old homemaker posted a smiling selfie with Natalia, 18, and her youngest daughters, 4-year-old Bianka and 2-year-old Capri.

But Vanessa's heart was breaking behind her big smile. "Today was rough. This was before the tears came down," she captioned the photo.

She added a message to her late husband, Kobe, and their daughter, Gianna, who tragically died with him in a helicopter crash last year.

"Missing [two fingers] forever. I love you @nataliabryant BE EPIC and FIGHT ON. [heart emojis]."

Natalia responded to her mom in the comments, writing, "I love you!!!"

Vanessa limited the comments under the post. But her VIP followers showed their support for Vanessa and Natalia.
