Actress Jessica Biel is refusing to open up about her on/off relationship with Justin Timberlake because she fears she'll lose the last "sacred" aspect of her personal life if she does.

The Hollywood beauty and Timberlake ended their four-year romance in March, but they have since reconciled and the SexyBack hitmaker recently confirmed the reunion, telling Vanity Fair magazine Biel is "still the most significant person in my life".

But The A-Team star is less forthcoming about her love for the singer/actor, insisting she prefers to keep talk about her high-profile relationship away from the media.

She tells Elle magazine she was flattered by Timberlake's remark, but she'd rather not open up about her private life: "It's obviously a beautiful thing to say. Absolutely, the feeling is mutual. But that's all I can really talk about.

"There's nothing that's sacred anymore... There's just a line that you have to say, 'I can't go any further'."
