Double date time!
The two couples opted for a late lunch at Pierre's before heading back to their beachside home.
Khloé looked adorably sporty in a tennis skirt, jacket and sneakers, while her rapper boyfriend was dressed down in a pair of sweatpants and a T-shirt.
Meanwhile, Khloé's expectant sis wore a plaid button down with skinny jeans and ankle boots.
The group has been spending lots of quality time together while the two E! reality stars film their upcoming Keeping Up With the Kardashians spinoff, Kourtney & Khloé Take the Hamptons.
And it seems that Kourtney and Scott have given their stamp of approval on Khloé's new man, too.
The loved-up duo were just in South Africa last weekend, where Khloé accompanied French at the 2014 MTV Africa Music Awards.
"They seemed happy—like teens in love," a witness, who spotted the pair Sunday at O.R. Tambo International Airport in Johannesburg, told us at the time. "French Montana was holding her tightly and they were laughing a lot."
They also went on a safari during their quick trip and snapped several pics on Instagram documenting the fun excursion.
French even shared a video of what appeared to be some natives performing a dance for their famous visitors, writing, "Sometimes you don't know how blessed you are. #grateful #southafrica"
