Lauren Sanchez, 55, outshines Sydney Sweeney, 28, at her own birthday party

Sydney Sweeney celebrated her 28th birthday over the weekend, but not all eyes were on the birthday girl at her star-studded party

While the Euphoria actress is famous for flaunting her jaw-dropping cleavage, she was outshone at her own birthday bash by none other than Lauren Sanchez.

The 55-year-old wife of Amazon mogul Jeff Bezos dared to bare by wearing a strapless metallic mini-dress that left little to the imagination.

Sanchez struggled to contain her curves in the skimpy silver number as she posed next to the birthday girl, whose own dress was slightly longer and less revealing than Sanchez’s.

People online couldn’t resist commenting on the brunette’s bold look, with one joking, ‘Bosom buddies!’

‘Lauren is too much,’ wrote another, while a third commented, ‘That dress is way too tight.’

Another wrote, ‘Lauren can always be counted on to look over the top. Literally!’

Sweeney threw a space-themed party with pals Glen Powell, 36, Wiz Khalifa, 38, Diplo, 46, and many more in attendance.
