Motherhood sure looks good on Kristin Cavallari!

Nearly one month after giving birth to son Camden Jack with fiance Jay Cutler, former Hills star Cavallari, 25, showed off her slender post-baby bod via Twitter as she celebrated a girls' night out with pals.

"Girls night!! Yes at 6pm haha," Cavallari tweeted Monday, along with an image of the new mama wearing a printed mini dress that showed off her sexy legs.

Though its unclear how Cavallari spent her time with pals, she unwound earlier with an unexpected luxury. "This mamma is gonna have her first glass of wine in 10 months tonight," she tweeted Sept. 1. "Woohoo."

Welcoming her first child August 8, Cavallari has had no problem getting back into the swing of her post-pregnancy diet. When one fan asked on Twitter, "Have you had your 'post-pregnancy sushi' yet?" Cavallari replied, "In the delivery room! Ha!" (Cavallari's Chicago Bears quarterback fiance, 29, also surprised his bride-to-be with a steak dinner after baby Camden's arrival.)

As she relishes first-time motherhood, Cavallari is already thinking about having baby No. 2. "We were talking about the possibility of having another kid right away and then getting married so we can have two kids close in age," Cavallari — who put her wedding to Cutler on hold until Camden's birth — tells Glamoholic. "We want four kids, so we're thinking maybe have one more, then get married, then have two more. But we'll see — it all depends on how the first one goes."
