Justin Timberlake's fiancee Jessical Biel had "no say" in the selection of her engagement ring, insisting she let the singer/actor pick out the sparkler because "he has better taste."

The "SexyBack" hitmaker proposed to The A-Team beauty in December with a large square-cut diamond surrounded by smaller stones and Biel admits the rock caught her by surprise, revealing she didn't give the 31 year old any design input.

She tells InStyle magazine, "I had no say whatsoever (in the ring). I don't micromanage. He is fearless in his choices and has a real eye for design. And I'll be honest, he has better taste than I do."

Fashion icon Timberlake also gives his athletic lover daily wardrobe advice.

She adds, "When I walk out of the closet after getting dressed in the morning, I'll go like this (turns palms upward as if to say, 'Well?') And he goes like this (shakes his head no). Then he picks again. It's hilarious."
