Josephine Skriver kicked off her ‘birthday week’ by flaunting her six-pack abs in a bikini at Encore Beach Club in Las Vegas on Saturday.

The Society Management model – who technically turns 24 next Friday – sipped champagne as she took a whirl on the EBC’s ferris wheel located inside Wynn Las Vegas.

Josephine was joined for a dizzying ride on the pint-sized attraction by three model gal pals.

The half-Dutch, half-Danish beauty – rocking a dotted triangle top with solid black bottoms – was nearly inseparable from her ‘sister’ Jasmine Tookes.

Skriver and the 26-year-old IMG Model both just happen to be Victoria’s Secret Angels. Jasmine earned her ‘wings’ in 2015 while Josephine, who’s been with the lingerie label since 2013, scored her ‘wings’ in 2016.

The beautiful BFFs partied in a VIP bungalow atop the three-tiered pool complex while DJ David Guetta manned the decks below.

And it wasn’t just the 5ft11in cat walker’s birthday. Her boyfriend Alexander DeLeon officially turned 28 on Saturday.

Josephine – who boasts 5.8M followers – gushed on Instagram: ‘Couldn’t be happier celebrating my love and man’s birthday! Every day with you is the craziest party and a dream come true!’

The Cab front man, who’s been with Skriver since December 2013, replied on Instagram: ‘Definitely in my top 5 list of favorite days ever!’

Skriver and her sizeable entourage – who were staying at Palms Casino Resort – later dined on fare prepared by Chef Joseph Zanelli at Jardin.
