FAMEKristen Bell hasn't been on Mars for awhile, but she's been lurking around clound nine.
The When in Rome star is engaged to live-in beau (and When in Rome stalker) Dax Shepard, E! News confirmed Sunday.
"They got engaged over the holidays," said Bell's rep.
Shepherd, 35, popped the question last month, about two years after he and Bell first stepped out as a twosome, according to Us.
A ring-less Bell hit the Grammys tonight with costar Josh Duhamel to present the award for Best Country Album to Taylor Swift.
