Kyle Richards is one busy later. In addition to running her boutique in Beverly Hills, the reality star is juggling her life as a mother of four with her duties as a wife and star of The Real Housewives of Beverly Hills.

In a new interview, Richards opened up about her life at home, revealing she's in back to school mode with her daughters.

"I am in full-blown back to school mode," Richards told Bravo TV's The Daily Dish. "Portia just started third grade. She's very nervous because she heard they get 'very strict' in third grade, so she's already scared."

"Sophia is going into 11th grade and this year we're going to be looking at colleges, touring schools, and it's really exciting. Kind of scary because that means she's leaving for college soon, but it's scary and exciting all at the same time," she continued.

Richards has four daughter, the oldest of which, Farrah, left the nest years ago.

"Alexia is going back to Boston [for college]. She's loving where she transferred. She's having the best time. It is such a beautiful city. I am obsessed with it. I love going to visit her, even though its freezing there I still love it so much," she said. "Farrah is busy at work at the Agency. She doesn't have back to school, lucky girl, but she works her butt off and is killing it."

As for Richards' husband, Mauricio Umansky, fans can catch him on the ninth season of Million Dollar Listing: Los Angeles, which airs on Bravo TV on Thursdays at 9 p.m.
