Earlier this week, Kim Kardashian and her youngest sisters, Kendall and Kylie Jenner, were spotted on the set of the upcoming blockbuster Ocean's Eight for what appeared to be a 'girls only' trip to New York.

However, it seems it didn't take long until the Jenner sisters decided to invite their other halves to the Big Apple to indulge in a spot of retail therapy.

And, of course, nothing says retail therapy like a shopping trip for diamonds, right?

On Tuesday, supermodel Kendall was spotted with rumoured boyfriend ASAP Rocky – who sported a bright purple fluffy cardigan for the trip– along with beauty mogul Kylie and boyfriend Tyga at Rafaello & Co., perusing the jewelry cabinets.

The Victoria's Secret model – who wore an olive green suede coat for the occasion – and the rapper were later seen at menswear clothing shop, Ovadia & Sons, where Kendall was spotted looking at the brands fur shoes.

Kendall is rumoured to have been dating the rapper for several months, despite being spotted with former flings including LA Lakers player, Chandler Parsons and One Direction singer, Harry Styles in recent months.
