Okay, how cute is Harry Styles?
The adorbs One Direction singer served as the best man in his mom's wedding this weekend, and he did more than just walk her down the aisle. He also serenaded her with Stevie Wonder's "Isn't She Lovely!"
A source told The Mirror, "Harry couldn't stop smiling. He hardly left his mum’s side and she looked really proud of him."
Hazza's always been close with his mum, and even said she's the only person he really tells about the girls in his life: "She knows the truth." Mama knows best, right? And she sure raised one heck of a good son!
