Kristin Cavallari is one red-hot mama-to-be!

The Hills star showed off her tiny baby bump Wednesday night at the premiere This Means War in L.A.

Drawing attention to her toned legs with a supershort hemline, Cavallari even rocked some sky-high nude, peep-toe stilettos with her sexy little red dress. The 25-year-old tweeted a picture of herself on the red carpet, writing, "U can see a little baby bump!"

But pregnancy hasn't been just parties and Twitter for the former Dancing With the Stars contestant….

She recently came under fire after defending Gisele Bundchen's harsh remarks about hubby Tom Brady's teammates after the Super Bowl.

"Kind of loving Gisele stuck up for her man," Cavallari tweeted, quickly finding a lot of people weren't a fan of the Brazilian supermodel's poor sportsmanship.

Cavallari quickly changed her tune. "I agree its not cool to throw teammates under the bus," she wrote. "I was simply saying its cute she had her mans back. Not at the teams expense though."

Fair enough. We just hope we don't hear Cavallari bashing fiancé Jay Cutler's Chicago Bears teammates anytime in the near future!
