Kelly Osbourne has been spotted looking smitten with new beau Matthew Mosshart, and it looks as if the pair are more serious than we thought.

"I'm in love and I don't care who knows about it!" the E! "Fashion Police" host tweeted Wednesday, quoting a Will Ferrell line from the 2003 movie "Elf."

Osbourne, 27, also tweeted a photo of the couple locking lips (or more accurately, tongues).

Mosshart, 28, is a vegan chef and the brother of Allison Mosshart of the band the Kills. The couple reportedly met at the 2011 wedding of Kate Moss and Kills guitarist Jamie Hince.

While Osbourne's rep shot down recent rumors that the couple was engaged, Osbourne did admit to having "baby fever" after meeting her new niece in May.

"I’d be the best mum ever," she told Anderson Cooper. "I would. I’ve got great training from my mum.”
