Kourtney Kardashian dons bust-enhancing bikini, bares belly button on Instagram

Kourtney Kardashian heats up Instagram for the holidays, baring her flat tummy in a figure-flattering bikini as she hints about spilling the tea.

Kourtney Kardashian, we’re ready for you to spill the tea! The Keeping Up With The Kardashians (KUWTK) showed her sense of humor about all that gossip involving herself, Sofia Richie, and Scott Disick in her Instagram caption.

But can we have a chat about that bathing suit, beauty?

Kourtney Kardashian dons her most figure-flattering bikini yet on Instagram

Kourtney looks fabulous in that swimsuit. The bikini top enhances her bust, and Kardashian must have searched to find the perfect match for her bikini bottom.

The bottom half of the swimsuit shows off that flat tummy for which Kourtney is famous. Kardashian lounges across two chairs (good for the abs, that pose!) as she holds her tea.

“Sexy and beautiful,” summed up one fan of the pose.

Kourtney has a smile that makes us think she knows something we don’t, and that caption adds to the impression!

“Almost spilled the tea,” she wrote, hinting at the temptation to spill some gossip.

Kourtney Kardashian ready to spill the tea yet?

So Ms. Kardashian, got some gossip, er, tea, to spill?

Actually, it’s Scott Disick who seems to be spilling the real tea these days!

Us Weekly pointed out that Disick (who shares three kids with Kourtney and has been open about his affection for girlfriend Sofia Richie) seemed upbeat about vacationing with Kardashian and Richie.

“What more can a guy ask for?” questioned Scott on the picture showing him with Kourtney and Sofia.

Sofia is 20, while Kardashian is 39. Kourtney’s baby daddy is 35.

Of course Disick isn’t the only one in this odd love triangle to have a history of dating younger people. Kardashian famously had an on-again, off-again romance with pop star Justin Bieber prior to his marriage to Hailey Baldwin.
