They’re always looking to expand their empire, and yesterday (June 9) Khloe and Kourtney Kardashian launched Kardashian Beauty at ULTA Beauty in Huntington Beach, California.

The “Keeping Up with the Kardashians” stars smiled and waved to their fans as they posed for the press and promoted their new goodies.

Playing the role of supportive sister, Khloe Kardashian accompanied Rob as he picked up his new socks collection in downtown Los Angeles on Thursday (June 6).

The youngest Kardashian sister wore a long-sleeved black top with cropped workout leggings while her baby brother sported a black T-shirt, shorts, and an L.A. Dodgers baseball cap.

Not afraid to put herself in an uncomfortable situation to help out her sister, Khloe Kardashian brought over some x-rated toys to Kourtney's house in Sunday's episode of "Keeping Up with the Kardashians."

During the season premiere, the eldest Kardashian sister's partner Scott Disick suggested the two vary their sex life with a form of sex that Kourt refused to consider.
