The 26-year-old Florence and the Machine frontwoman said that she is always happy to try any product her grandfather recommends, reported Contactmusic.
"My beauty guru is my grandfather. He is a very stylish gentleman and always drilled into me that Kiehl's was the best. I swear by their Ultra Facial Cleanser," Welch said.
The singer, known for her elaborate stage outfits, says she chooses her garments depending on how well they can 'perform' on their own.
"I like opulence and drama and want an outfit that does a performance of its own. Light fabrics are great outdoors because they throw themselves around with the wind," she said.
