Biel admits she and her SexyBack hubby-to-be haven't actually started planning their big day.
"Everyone's been telling us, 'Enjoy the engagement because it goes away so quickly,'" the 30-year-old starlet exclusively told us last night at the premiere of her new movie, the reboot of Total Recall (in theaters tomorrow). "So I've been sort of loving that idea."
While we can't wait to see Biel in her wedding gown, she definitely looked fab on the red carpet last night in a pink Dior dress and oversized necklace.
However, if Biel's not careful, she could find her tight and toned Total Recall body getting soft.
Did you know the former 7th Heaven star loves to bake? Banana bread with bluberries, she said, is her speciality.
"I don't eat all of it," Biel said. "I have a bite to see if it's good and I write a little note on my recipe pad. Then I give it to my friends."
Yes, Timberlake, 31, is a fan of her homemade sweets. "But his granny is way better than me," Biel smiled. "And he'll tell me that straight to my face."
OK, maybe Biel's not that tough. She laughed, "I feel like a bad ass, but I just don't know if I actually am one—at least not in real life."
