Although the Hot Pursuit star is celebrating her children's latest milestones, she shared that balancing a career with three kids can get a little tricky. During an interview last August with Southern Living magazine, Reese said, "No one’s really doing it perfectly. I think you love your kids with your whole heart, and you do the best you possibly can."

Reese on the importance of family

She continued: "There are some sacrifices you make, and it hurts your heart sometimes, but my kids tell me they’re proud of what I’ve accomplished, and that just means everything. I grew up with a working mom, and I have so much respect for the things she did as a nurse and a teacher. I would never begrudge her that."
