Just days before tying the knot with Jeff Bezos in Venice, Lauren Sánchez may be dealing with a last-minute beauty hiccup. According to a source, celebrity nail artist Iram Shelton was listed as a “no show” on a guest log photographed at the airport — raising questions about who will do the bride’s nails.

Shelton, known for her flawless work alongside celeb nail guru Tom Bachik, was rumored to be Sánchez’s top choice for her big day.

Meanwhile, preparations for the wedding of the year are in full swing. The couple reportedly rented out the entire Aman Venice Hotel, even displacing prior guests — who are being moved to the St. Regis with upgraded stays.

Sánchez, 55, kicked off celebrations last month with a glamorous Paris bachelorette bash alongside Kim Kardashian, Katy Perry, and Eva Longoria.
