Matthew Mosshart Kelly Osbourne LAX sunglasses fashion police purple hair

Kelly Osbourne and her beau Matthew Mosshart landed at LAX over the weekend, and the lovebirds have been together for over a year, but they look like they're still in the honeymoon phase!

"Kelly's family loves her boyfriend," a source told Us Weekly last month. "They think he's the nicest guy she's ever dated. He is very patient and down-to-earth ... She tends to be kind of a diva. So his sweet nature is good for her." The insider added, "Kelly is the happiest she's ever been. Her career is going well, and she's in a healthy relationship with a wonderful guy."

The vegan chef even moved from New York City to Los Angeles be with Osbourne, so you know it's serious! Maybe someone will be getting a ring this Christmas?
