"I had no say whatsoever [in the ring]. I don't micromanage," she told InStyle, on newsstands this Friday. "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."

"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," said Biel.

Also in the interview, Biel gave relationship advice.

She said the key thing for having a happy relationship is "letting go of the little stuff. You can't let it get to you." Plus, being with an inspiring person is a key to her happiness. "It is important to me to have a partner who is loving and fun - someone who inspires me," she said. "And he must be a good person."

Biel said she learned a lot about relationships growing up by watching her mom and dad, reported People Magazine.

"The best thing I learned from [my parents] is that you have to put your relationship first. You need to make time for your partner," she says. It's really easy to let that go by the wayside. It's easy to say, 'Hey, I'll see you later. I love you.' And you can't do that."

The beautiful actress said that with earlier experiences, she was really vulnerable in relationships to "somebody else's personality, hobbies and way of life."

"But as I've gotten older, I've become proud of the traits that make me who I am. Maintaining my individuality is really important to me because otherwise I can easily slip into somebody else's life. So I'm glad I'm getting better at it. It's a process, but it's getting simpler."

According to Entertainment Wise, Biel and Timberlake got engaged in December 2010. Sources from US Weekly said that they are planning a very big wedding for this summer.
