My dad puts everyone before himself. He makes sure we have a roof over our head and food on the table. The number one thing he's taught me is family always comes first and is the most important thing in life. My dad works blacktop and works long extremely hard days,. My dad deserves a break from the heat and a treat to cool himself down. He's always tired and overheated but still keeps pushing I'd do anything to see my dad cooled and relaxing, he does so much for us this would be the most amazing gift.
Taylor Swift took home top honors at The Fragrance Foundation Awards and won the Fragrance Celebrity of the Year Award for her Wonderstruck and Wonderstruck Enchanted scents.
Swift said: "My first fragrance, Wonderstruck, was all about a daydream, a fantasy. It was this romantic idea that we all have. I think that beginning with a lyric was one of my favorite parts about creating it, because I love telling stories and building and adding pages as we go. This is a really nice page to add to that story."
Taylor feels it might be "shameless" to promote her own products, but her new favorite scent is the one that's coming out soon, Taylor by Taylor Swift.
Justin Bieber also won two awards for Women's Consumer Choice Award and Popular Fragrance of the Year Women, for his Girlfriend scent.
