Kristin Cavallari has already lost 20 pounds of pregnancy weight a little over two months after giving birth to her second child.
Their first son, Camden, was born in August 2012.
"I'm still a couple of pounds away from my pre-pregnancy weight, but it took a solid three months with Camden and I think it will be the same this time," Cavallari revealed.
How did she do it?
"I started working out when Jax was three weeks old. I've been working out four to five times a week for 30 to 45 minutes at home, doing tons of leg work like squats, lunges and lifting weights," Cavallari said.
She's had impressive results and doesn't seem worried about those last few pounds.
"My stomach needs the most work but that takes time more than anything and diet plays a huge role."
Cavallari didn't change up her diet during her pregnancy but instead consistently embraces clean eating:
"We eat a ton of veggies, chicken, grass-fed beef, bison and fish. We also love sweet potatoes and brown rice pasta. I either make a smoothie, oatmeal or eggs for breakfast and a salad or turkey sandwich for lunch," she said. "I have a snack in the afternoon - usually nuts with dried cherries, chips with hummus, or an apple and almond butter. I also love avocados with olive oil and sea salt and I put coconut oil in or on everything."
Born in Denver, CO, Cavallari relocated to a Chicago suburb with her mother following her parents' divorce. By the time she was in high school, she'd moved to California to live with her father.
Not long after that she joined the cast of the reality series Laguna Beach: The Real Orange County in 2004.
In 2009 she moved to the spin-off series The Hills, where she remained for two seasons.
Cavallari was a contestant on season 13 of Dancing with the Stars, partnered with professional dancer and series veteran Mark Ballas. The pair was eliminated relatively early, much to everyone's surprise, ending up in 10th place overall.
Speaking of shoes, while pregnancy and motherhood may not have changed Cavallari's diet, they have influenced her fashion choices:
"I definitely wear a lot more flats than I used to. It's too difficult carrying babies in heels. It makes me nervous!" she said in a recent interview with Glamour.
