She's a critic in the making! John Legend's daughter, Luna Simone Stephens, isn't afraid to show her dad what she thinks of his vocal warmups. On Wednesday, July 11, John's wife, Chrissy Teigen, shared a funny video on Twitter of her daughter listening to the Grammy-winning star's singing. Watch the video above to see Luna's hilarious reaction!

In the video, John began to warm up his vocal chords by singing a few notes, but as soon as his daughter heard his voice, she knew that she had to put an end to it. The tiny tot approached her father and yelled, "no, no, no," as John continued to sing.

"#TWO," Chrissy captioned the video and although she loves being married to her husband, she has admitted that there are some things that she can't stand about John like his vocal warmups. "I know he has a beautiful voice and I know I am 'soooooo lucky' and blah blah blah but John's vocal warmups make me want to stab my brain," she once jokingly said on Twitter.

Luna definitely inherited her mom's up-front attitude, so she'll most likely grow into a very strong, beautiful, and successful young woman. Chrissy and John are also parents to their newborn baby boy, Miles Theodore Stephens. John previously opened up to People about his daughter's thoughts on being a big sister.

"[Luna's] used to having us to herself. I think she's just starting to realize though that he might be competition," he said. "So in some ways it’s good because she's stepping her game up. She’s being more loving, she’s singing louder, and dancing harder. She's making sure we don't stop paying attention to her."

Luna will always be the apple of her parents' eyes, but John knows that there is also a big responsibility that comes with raising a son. "I think it’s kind of a special privilege for me to raise a young man. I want to try to give him the best advice and be a good man," he told People. Just don't let Miles hear your vocal warmups!
