Kristin Cavallari has reached the point of immobility in her pregnancy, but luckily, her fiance, Jay Cutler, knows a thing or two about pampering the mommy-to-be!

"Jay is making me lasagna...he takes such good care of me. Good thing, because I can barely move," Cavallari, 25, tweeted on Monday.

Still, even with her large baby bump on display, the star seems to have kept her slim figure in tact. Of course, it hasn't been easy, especially considering the fact that she has had to make some dietary sacrifices, such as raw seafood.

"Counting down the days until I can have sushi," she posted to her Twitter last month.

Cavallari and her Chicago Bears quarterback beau, 29, are expecting a baby boy in the coming months. They announced their happy news back in January, just two months after announcing their nuptials were back on. (They previously called off their engagement in July 2011.)

"The past year has been interesting," Cavallari told Us Weekly at an Alice + Olivia event in December. "There have been a lot of ups and downs, but overall it's been great."
