The former The City and The Hills star smooched her producer man under the mistletoe while filming a chewing gum commercial.
Well, we suppose it was work, given they're promoting Orbit, but still, it's more fun than a day at the office, right?!
Whitney and Tim are gearing up for their second Christmas as an engaged couple, after Tim popped the question last year.
Tim proposed to Whitney during a holiday to Australia at the end of the year, getting down on one knee in their hotel room.
Whitney later told E! News: "It was super intimate. We went home the next day. I love the ring. It's beautiful! I knew he was the guy for me, but it wasn't something that I had been expecting."
Her family had been expecting it, however, as Tim asked every single member of her family for their permission beforehand!
Whitney recently told People that she's "taking her time" over the actual wedding and enjoying planning it, rather than rushing down the aisle.
"I already know that I'm going to be with him forever, and I feel completely confident in that. I don't need that label. But I just think it's exciting to be in this next chapter of our lives, as cheesy as it sounds," she said.
Whitney and Tim met on the set of MTV show The City, where Tim was working as an associate producer.
