Kim Kardashian was looking red hot in a beige bikini as she celebrated her 40th birthday this week. The Keeping Up With the Kardashians star posted a slideshow of photos from a recent beach trip on October 26, each snapshot steamier than the last.

At 40 years old, Kim has never looked better!

As reported by the Daily Mail, Kim is currently enjoying a secret birthday vacation with family, and while she hasn’t disclosed her whereabouts, it looks like a tropical dream. Kim’s photos showed her standing in crystal blue waters, with palm trees and white sand behind her.

Kim opted for a beige-colored string bikini for her beach day, pairing her look with large mirrored sunglasses and a Louis Vuitton scarf on her head. She’s reportedly said to be spending time on a private island, the Daily Mail added.

Kim celebrated her milestone birthday for a special episode of Keeping Up With the Kardashians, and received the ultimate surprise birthday bash from her family. The KarJenner clan banded together to throw Kim a party that was the ultimate nod to her past. They set up a fake Tao Nightclub in the venue (one of Kim’s former favorite birthday spots) and even performed one of their favorite childhood dances. Kim’s fam also shared throwback home videos on a projector screen throughout the night.

After the episode aired, Kim shared a message of gratitude to Instagram.

Kim Kardashian also celebrated her special day with a new KKW Beauty release. She launched her opalescent collection last week, sharing a promo photo of herself sitting in front of a massive cake.

40 has never looked so good. Cheers to another year of health and happiness to the mom-of-four!
