Kim Kardashian and Ivanka Trump had a fun time in Sin City. The two friends attended the grand opening of Groot Hospitality’s establishments: Komodo, Papi Steak, and Liv Las Vegas at the new luxurious Fontainebleau Las Vegas resort.

The former first daughter was dressed in a strapless Monique Lhuillier top and a skirt with silver inserts. Meanwhile, the 43-year-old Kardashian stunned in her form-fitting black knit dress and diamond necklace.

Ladies’ night in LV! Trump captioned the photo with the Skims founder on her Instagram. ‘Always a wonderful time with you, @KimKardashian,’ she noted under another photo.

Lately, Kim and Ivanka have become close friends: Trump attended Kardashian’s birthday party in September.

Kardashian, Trump, and the rest of the team continued the evening at the Liv nightclub. ‘Ivanka stuck close to Kim,’ reported a source to Page Six. Kardashian and Trump laughed throughout the night, and both left well past midnight.
