Obviously, sometimes sisters just can't help but be alike.
Kourtney Kardashian and sister Khloé stepped out in the Hamptons today in similar workout outfits and managed to wear the same expression while going about their business.
Kourtney, who's apparently getting a jump on prenatal fitness, concealed her barely there baby bump with her zipped-up hoodie, worn with cropped leggings and sneakers.
Khloé, back from a quick trip to South Africa to be with French Montana, also wore a sweatshirt, cropped leggings and sneakers, casual wear that transferred earily from the gym to the nail salon for a manicure.
She was in Africa when all the excitement went down Sunday after the season premiere of Keeping Up With the Kardashians, which was capped off by Kourtney finally confirming that, yes, her third child with Scott Disick is on the way!
The sisters' adventures will be chronicled in the upcoming E! series Kourtney & Khloé Take the Hamptons.
Their home base for the summer is a $13.9 million waterfront estate in Southampton that rents for $70,000 a month. Plenty of room for Mason and Penelope to run around and to accommodate visitors like Kim Kardashian, who has said that she plans to spend some time with her sisters in New York.
And don't miss the lead-up to Kim's wedding on new episodes of Keeping Up With the Kardashians, Sundays at 9 p.m. on E!
