KOURTNEY Kardashian posed in a barely-there bikini as her romance with Travis Barker heats up.
Kourtney, 41, recently flew to Turks and Caicos with her sisters.
The oldest Kardashian sister took to Instagram on Sunday to show off her curves as she posed alongside friend Victoria Villarroel.
The two friends rocked matching two-piece bathing suits with mustard hues as their dark hair flowed freely down their backs.
Along with the serious of sexy photos, the mom of three wrote: “Double trouble.”
The vacation comes just days after a source revealed that Kourtney had begun dating Blink 182 drummer, Travis Barker.
The Sun had exclusively reported that the two were getting closer after he left a flirty comment on one of her Instagram pictures.
A friend close to the new couple told us: “Kourtney and Travis are very close and they have unreal chemistry.
“They talk almost every day and everyone around them is desperate for them to get together.”
Fans had previously spotted a flirty exchange on Instagram between the pair when Kourtney posted about the musician’s favorite movie, True Romance, as he commented, “You’re so cool.”
Kourtney also splashed out $795 on a rare Prada bag for Travis’s daughter Alabama.
The insider said: “It was a very interesting gift for Travis’s 15-year-old daughter – it’s the same bag Kourt bought Khloe for Christmas.”
Despite Kourtney’s family and friends approving of the new relationship, her baby daddy, Scott Disick, is actually jealous and furious.
“Scott and Kourt’s relationship is still very close – unusually close considering they split over five years ago,” a friend close to the former couple told The Sun.
“He has a key to Kourt’s house, and comes and goes as he pleases, sometimes twice a day, and still considers Kourtney his family.
“Yes, they’ve both dated other people since they broke up, but it’s never been an issue as it’s always been younger models, and not serious relationships.”
The source added: “But now Kourt is officially dating Travis, Scott’s suddenly really jealous and seems furious.
“He’s always asking Kourt about Travis and I think he’s secretly worried about what will happen – will she try and push him away? Will the Kardashians still consider him their family? Will Travis be the new father figure in his kids’ lives?”
Kourtney and Scott children Mason, 11, Penelope, 8, and Reign, 6.
