The "Total Recall" star - who has two-year-old son Silas Randall with husband Justin Timberlake - loves being a mother and says it has informed everything in her life, reported E! News.
"I don't know if that sounds kind of goofy. I just feel like I'm always ready for anything and everything at this point. Motherhood informs everything in your life. I'm more emotional, more sensitive, more everything to the world."
Meanwhile, the 35-year-old actress previously revealed she doesn't want her son to follow in his parents' footsteps and join the showbiz industry.
