Cheeky Hailey Bieber serves ‘body goals’ in thong bikinis during Kendall Jenner’s birthday getaway

Hailey Bieber got cheeky in a series of thong bikini snaps from Kendall Jenner’s tropical birthday getaway.

The rhode skin mogul was pictured taking in the seaside scenery in a skin-baring green thong bikini, in an Instagram carousel published Thursday. In another snap, she modeled her backside in a similar black thong bikini.

She was also seen sharing a kiss with the birthday girl in an animal print minidress, hanging onto the side of a small boat, and snuggling up with pals for a bikini-clad selfie.

One steamy photo showed the mom of one, 28, sharing a moonlit beach kiss with husband Justin Bieber — with whom she shares baby Jack Blues, 1 — as they celebrated the “Kardashian” star’s 30th.

“hell yeah !” the supermodel captioned her personal photos from the celebration, which took place on Monday at a private beach villa in the Caribbean.

Hailey also appeared in a black thong bikini in a group snapshot shared by Carter Gregory on Thursday, alongside birthday guests Justine Skye, Victoria Villarroel and Stassie Karanikolaou.

In the comments thread of Hailey’s Instagram upload, fans raved over the model’s pics.

“Mamacita 🔥” one person wrote, while another added, “Gorgeous gorgeous girls.”

“The hottest mother ever ❤️‍🔥 Jack’s mom is so iconic,” gushed a third, with a fourth chiming in, “WE NEED A STRONGER WORD THAN DIVA.”

One person complimented her “glowing” makeup-free skin, while another praised Hailey’s “body goals.”

Jenner’s star-studded beachside soirée — which was also attended by mom Kris Jenner and sisters Kylie Jenner, Kim Kardashian and Khloé Kardashian — featured a massive fireworks display.

It also included silver balloons spelling out “Happy Birthday Kendall” and a bottle of 1995 Chateau Haut-Brion French red wine, commemorating Kendall’s birth year.

A beach bonfire — surrounded by pillows, individual rugs and glimmering lights — lit the festivities.

Following the beach bash, Hailey took to Instagram to share a photo with Kendall and Skye. “I love you my sweet beautiful best friend,” she wrote atop the pic, adding, “We really doing this life s–t together. Forever!!!!!”

Kendall herself took to Instagram on Wednesday to share a carousel of similar skin-baring snapshots from the getaway — including a fully nude pic on the beach.
