Paris Hilton and Cy Waits went shopping for an engagement ring in New York City on Friday (18.02.11)

The loved-up couple were spotted in jewellers Jacob & Co. looking at several different sparklers, including a rare 30-carat blue diamond.

Despite inspecting the betrothal bands, the pair don’t have any happy news to announce just yet, but Paris did leave the store with a $25,000 black diamond-encrusted ring for her 30th birthday – which was on Thursday (17.02.11).

However, the hotel heiress insists it won’t be long until she and Las Vegas club owner Cy do commit to one another.

She told the New York Post newspaper: “We’ve talked about it (getting engaged). This is once in a lifetime. I want to be with him forever. And Cy has great taste. He just bought me a beautiful sports car.”

Paris was referring to the white Lexus LFA convertible supercar her boyfriend bought her for her birthday.

The blonde beauty topped off a week of partying by meeting her friend Denise Richards at Asellina restaurant on Thursday, before joining her family for a celebratory meal at top eatery Lavo.

Paris had one of her birthday cakes stolen by a musician known as ‘Paz’ from her Hollywood party on Tuesday (15.02.11).
