Probably a good thing that Luna loves her dad's music, since Teigen already revealed that Legend isn't so great with the conventional lullabies. As she recently told People , Legend needs a lesson in how to sing to babies.“I gotta say though, if you could listen in, some of them are pretty questionable,” she joked with the magazine. “He doesn’t really know how to sing to babies … [The] bath time song wasn’t so good, I will say, last night, it was like, ‘You’re taking a bath time.’ Like, there was just no thought into it.”Luckily, Legend seems to be putting all his musical prowess into his real music, which is made for adults, but perfect for babies, too.
