Jessica Biel cannot hide her pregnancy anymore. Her growing baby bump was clearly visible during her recent outdoor activity although she seemingly tried to hide it under her navy sweatshirt, which was paired with black bubble vest, gray sweatpants as well as pink and blue sneakers .

The wife of Justin Timberlake was taking her two dogs for a walk in Los Angeles on Friday, December 5. Wearing a pair of sunglasses, the 32-year-old actress was all smiles when paparazzi took her pictures.

Biel and Timberlake, who tied the knot in October 2012 after dating since January 2007, remain mum despite persistent reports about their pregnancy. A source previously told Us Weekly, "Right now they are just enjoying the news for themselves. They just want a happy baby."

Another source said the "7th Heaven" alumna kept her pregnancy a secret because she "has had tense times in the past when it comes to having a baby. So it is not surprising that she is staying mum on confirming the news publicly yet."

She is reportedly due in April 2015. The baby will be the first child for the couple.
