Kate Beckinsale is one proud mama!
The actress shared a side-by-side photo of her 17-year-old daughter Lily on her first day of school vs. her "last first day of school" as the teen begins her senior year.
"Love you so much," the 43-year-old captioned the pic, no doubt embarrassing her only child.
When asked about life with a teen, the brunette beauty previously said, "I had a child young enough that it doesn’t feel too far away from my own experience. I feel like I flunked at adolescence really badly... I think it’s a very difficult time, but she’s doing great.”
