Paris Hilton and boyfriend Cy Waits may soon be getting engaged, reports People.  The couple were spotted shopping at Jacob & Co. jewelry store in New York City on Friday. “They shopped for engagement rings,” says a source. “They were really cute together.  Paris was making comments about the rings and joking that her ring has to be at least 24 carats.”  While the pair did not leave the store with an engagement ring, Hilton did “[walk] out sporting a $25,000 white gold and black diamond ring.”  Hilton’s rep later revealed, “The couple were shopping in New York looking for something special for Paris’s 30th Birthday.”

How can you tell when your mate is about to propose?

Cupid’s Advice:

While most women are surprised when their partner pops the question, some are ready and well-prepared.  Here are a few ways you can tell when your man is about to propose:

1. He asks your opinion: When he casually asks for your opinion on restaurants or even on jewelry, it may be a sign that he’s about to pop the question.  He could be on a mission to find a special setting and the perfect ring.

2. Your rings are missing: If you find one of your rings missing one day, don’t panic.  Chances are, he’s taking the ring to a jeweler in order to find an engagement ring that will fit your finger correctly.

3. His behavior changes: If your partner is about to propose to you, he’s probably extremely nervous, excited or both.  You may be able to pick up on his changing behavior and mood swings.
