Nicknames for your significant others?

I'd love to hear some nicknames you and your significant other have for each other. Is it cute, personalized, silly, etc.? What's the story behind it? :) Feel free to post pics along with your comment if you'd like!

My name is Shefali and a lot of people call me Shef for short. My boyfriend began calling me chef-d'œuvre (which means "masterpiece" in French haha I think it's clever because I adore puns) . His name is Philippe (pronounced: Phil-ip) and he's québécois. Some of his friends call him Philou. I want to find a cute/fun nickname for him that plays with his name, but I'm having the hardest time coming up with something. Any suggestions?
