For those of you keeping score at home, Paris Hilton has been engaged twice (to Greek billion-heir Paris Latsis and model Jason Shaw) and declared two previous boyfriends husband material (Doug Reinhardt and Benji Madden).
Now, with a new reality show and an iPhone app to promote, the formerly ubiquitous starlet is once again playing the marriage card, this time with her squeeze of a little less than a year, Cy Waits. On Friday, a day after her 30th birthday, Paris hit high-end New York jeweler Jacob & Co. to eyeball finger-decorating baubles with Waits.
"They shopped for engagement rings," a source helpfully informs People. "They were really cute together. Paris was making comments about the rings and joking that her ring has to be at least 24 carats."
Because anything less than 24 carats would look out of place in that $375,000 Lexus roadster she received (on camera) as a birthday gift from Waits, who lost his lucrative Las Vegas executive gig after the couple's August drug arrest.
According to the New York Post, a certain bright and shiny object really caught Hilton's attention: a 30-carat rare blue diamond.
The outing came soon after Paris told Ryan Seacrest how certain she was her beau would propose (potentially punny wedding theme: true love waits).
Alas, she left the store without an engagement sparkler, but she did score a $25,000 white gold and black diamond ring.
"The couple were shopping in New York looking for something special for Paris' 30th birthday," her rep tells the mag.
"We love each other very much," Hilton assured Seacrest, before causing Fate to give an over-the-top eye roll by proclaiming to the Post, "This is once in a lifetime. I want to be with him forever."
