Nice job, K-Cavs!
And the 25-year-old did not disappoint! Hosting the ULTA Beauty "Donate With a Kiss" event at the James Hotel in downtown NYC, Cavallari flaunted her svelte post-baby body in a sexy cocktail dress and stiletto heels; engaged to Camden's dad, Jay Cutler, the new mom beamed for photographers and worked a fresh-faced makeup look, her blonde looks in loose, waves.
The Big Apple bash helped promote Ulta Beauty's new campaign to benefit Breast Cancer Research. (Learn more about giving at ulta.com/donatewithakiss.)
Famous for her bikini bod, Cavallari has been working hard to lose the baby weight. "Walking uphill on the treadmill to work out this booty," she tweeted Sept. 13. "Bye bye baby weight."
She and Chicago Bears quarterback Cutler, 29, got engaged in November 2011 after a brief split; no word yet on their wedding date.
