It's been a roller-coaster ride of a year for Kat. She started dated famed DJ Deadmau5, even giving him a star tattoo under his eye to go with her very own trademark. They split in November, but then he proposed in December...over Twitter. Huh. Nothing says "I love you" like social media! But she accepted, so we guess it's all good.

Today the tattooist turns 31 years old, so to celebrate we've decided to take a look at 15 of her most famous celebrity clients. You'll be amazed who has gone under Kat's skilled hands!
