Biel's having a baby! Jessica Biel is pregnant and expecting her first child with Justin Timberlake, multiple sources reveal in the new issue of Us Weekly.

"Right now they are just enjoying the news for themselves," one pal tells Us of the Blunderer actress, 32, and Timberlake, 33, who dated on and off for five years before getting engaged in January 2012. "They just want a happy baby."

Family is important to the couple, who celebrated their two-year wedding anniversary in October. "It's weird because it feels like almost nothing has changed, yet something that you can't really describe, or something that isn't tangible, has changed," Biel told Ellen DeGeneres of married life after returning from her honeymoon in 2012. "It just feels incredible."

Her spouse shared the same sentiment when seated next to DeGeneres in April 2013. "It's nice to marry your best friend. It suits me," the former 'N Sync singer said at the time. "Every once in a while I can catch a glimpse of her when she doesn't see me looking, and I have this moment where I'm like, 'If you never make a good decision…if you only make bad decisions for the rest of your life. You made one really good decision.'"

Both soon-to-be parents have juggled busy schedules this year, with Biel often accompanying Timberlake on the road for his 20/20 Experience tour. Last month, the 7th Heaven alum was photographed in a black bikini while in Hawaii.

Luckily for Biel, pregnancy cravings won't be an issue once Timberlake returns home. "He bakes pies. He's Southern, so he's got all this influence from his grandma," Biel said of the dad-to-be to Elle in January 2013. "He does a three-layer pie…and blueberry crunch cake, which is pretty unbelievable. It doesn't happen all that often, thank God. Otherwise, it would be a big problem."

"[Marriage] means always having someone there to open the pickle jar," she added to the mag. "To share the ups and downs with, have adventures with. Someone to go swimming naked with. That kind of thing."
