Paris Hilton “Sure” Cy Waits Will Propose

Paris Hilton has been in a sex tape and many serious relationships, but might Cy Waits finally be the one? According to reports, she’s absolutely sure of it.

She said the same thing about Doug Reinhardt, but no matter.

Paris recently told Ryan Seacrest that she’s sure Cy will pop the question. Based on a recent shopping adventure, that could be sooner than later, too.

On Paris’ 30th birthday, she accompanied Waits to luxury jewelry store Jacob & Co. in New York City, where the duo checked out some serious bling.

“They shopped for engagement rings,” the source says.

“They were really cute together. Paris was making comments to Cy about the rings she liked and joking that her ring has to be at least 24 carats.”

There was no engagement ring on this trip, but Hilton did not leave empty-handed. Girlfriend left with a $25,000 white gold and black diamond ring.

Not bad for a birthday. Paris told E! News that the two are “really serious” and that “I’m so happy. I’ve never been happier.” Pop it, Cy. Pop it.
