Kourtney Kardashian in Miami with Scott Disick

The Kardashians are coming! The Kardashians are coming!

Khloe‘s here and so is her big sister Kourtney, who arrived in Miami with her three kids and estranged boyfriend Scott Disick in tow. On Wednesday, paparazzi caught Kourt looking fit and fabulous in a yellow bathing suit on the beach; Disick didn’t look like his usual, buff self. Are they back together?

InTouch reports the longtime couple — who split last year after pictures surfaced of Lord Disick someone other than the mother of his children — are “secretly hooking up.” “They’ve been sleeping together for the last month on-and-off,” a source told the magazine.

“Both agree the sex is better than ever. Scott’s been staying over at Kourt’s and sneaking out early in the morning.” On Tuesday night, Kourtney and Khloe dined at Komodo — maybe they’re just fans of names that start with “K.”

Or it could be that pal Dave Grutman owns the restaurant. Various siblings attended the club owner’s wedding back in April. Guess who else is likely on her way? The queen of the family — Kim Kardashian. Her husband Kanye West will be performing in concert Friday and Saturday nights at AmericanAirlines Arena. Oh, praise Yeezus. It’s a family reunion!
