The party never stops! Not for the Kardashians, anyway.

After spending Kourtney Kardashian's 37th birthday in Iceland earlier this week, both she and her younger sister, Kim Kardashian, kept the party going in Miami.

Kim showed off some major cleavage in an Instagram selfie taken Saturday night, which shows her all dressed up in a lace number and diamond choker while her husband, Kanye West, sits beside her in the car. 

Both Kardashian sisters and West were in Miami to attend the wedding of David Grutman, owner of Komodo restaurant and the LIV and STORY nightclubs.

The Keeping Up with the Kardashians stars were joined on the getaway by Kim's husband, Kanye West, their daughter, North West, and Kourtney's daughter, Penelope Disick. Even though they were in Florida to celebrate a pal's nuptials, they turned the focus to Kourtney again on Friday night, going out to dinner with friends Jonathan Cheban, Simon Huck and Stephanie Sheppard, model Isabela Range and entrepreneur Jason Binn, plus Kourtney's BFF, Larsa Pippen.

And yes, despite it being their pal's wedding weekend and Kourtney's second round of birthday celebrations, Kim was most definitely center stage, even blocking Kanye in another group shot. 

Kourtney looked fierce in her form-fitting dress and seemed to have no concerns about digging into her monster cake, which featured a cute sparkly "K" on top, though both she and Kim admitted the five-tier present was extravagant.

Kim and Kourtney flooded social media with even more pics from yesterday's dual celebration, including this one of Kim taking a #bathroombreak:
