The 'Girl on Fire' hitmaker, who has son Egypt with husband Swizz Beats, said family life has made her more sure of herself and more comfortable than ever on stage, reported Contactmusic.
"Stepping into motherhood and becoming a wife, I've definitely become more confident. I can express my feelings more honestly.
"When you're trying to find your way, you hold so much back. Now that wall has gone, I've really stepped into myself. I am able to be more vulnerable and more composed. I just feel calm and comfortable with the shows now," she said.
"It's made everything a deeper, fuller experience in every way. I'd thought about it before but it wasn't really on my radar until I met the love of my life," she said.
