AceShowbiz - Seal accidentally ruined a birthday surprise for his wife Heidi Klum after the supermodel found her present stashed away. The "Kiss From a Rose" hitmaker purchased a new piece of jewelery for Klum, who turns 37 on Monday, June 1, but his plan to present her with the ring was foiled when the German beauty found the hidden treat.

She tells EOnline.com, "It's a pretty flower ring. My husband was going away and he asked me to help him pack a little bit. We were in his closet, and I was looking for things for him to take. I open this box and there's this gorgeous little sparkler in there that was looking into my direction!"

The Victoria's Secret star insists she has no party plans - she just wants to spend the day with the singer and their four kids, adding: "(I'll) go to dinner with my husband, (something) low-key. I like to plan for other people; it doesn't really have to be for me. I like to plan for the kids' birthdays."
