Evan Ross is absolutely loving fatherhood and marriage!
The 27-year-old actor, who just celebrated his first year of marriage to Ashlee Simpson, with whom he has a beautiful 1-month-old daughter, Jagger Snow, opened up to ET at People's Ones to Watch event at Ysabel in West Hollywood, California, about how much family life has taught him about love.
"I've been wrong a long majority of my life," Ross said about what he's learned since tying the knot. "The biggest thing in this world is in love. I'm so in love. I love my daughter, I love my wife. She's given me the best gift in the world. I'm very lucky."

So much love! Evan calls being a dad a "beyond life-changing" experience, too.
"She's the most beautiful thing you could ever think of," the actor gushed about his daughter. "I'm proud to be a dad, and I'm going to make sure she knows she's loved, and that's all I can do."

Meanwhile, Evan and Ashlee are proving they are more than just soulmates -- they're actually working on a song together!
"We have a song together called "Permission to Love," and we've been working on music for a while," he said. "She's so talented, whatever she can give me I'll take."
This is too much! You're too sweet, Evan!!
