Actress Jessica Biel had sparked pregnancy rumors last month when she was photographed with what looked like a baby bump. The 32-year old star was then shopping with a friend at the American Party Store in West Hollywood.

Biel's husband, 33-year old singer and actor Justin Timberlake, also attended the amfAR Gala in Los Angeles without the actress, which people thought was rather unusual and more likely due to the fact that she is currently with child.

Speculations grew when the star's good friend, InStyle Editor Ariel Foxman, posted a Throwback Thursday photo on social media and congratulated Biel on her pregnancy.

"Congrats @jessicabiel on your impending motherhood... Looking forward to the red carpet maternity style pic to come #tbt. (sic)," Foxman wrote.

So far, reps for both Biel and Timberlake have yet to comment on or confirm the baby news.

However, an insider said the couple, who just celebrated their second wedding anniversary, has not made any announcements because they want to enjoy the baby news in private for now.

"They just want a happy baby," the source added.

The couple has reportedly been trying for a baby for a couple of months, and that the actress has even gone to a fertility expert to help them conceive.

"She has no problem using technology, if that's what it will take to have a baby and stick this marriage out," the insider shared.

Biel and Timberlake began dating in 2007, but temporarily ended their relationship in March 2011. The pair eventually got back together and got engaged in December 2011. They married in October 2012 at the Borgo Egnazia resort in Fasano, Italy.

In the June 2011 Vanity Fair issue, even before they were officially back on again, Timberlake said, "She is the single-handedly most significant person in my life."
