It looks like we've got another celebrity baby bump watch here! Rumor has it that Justin Timberlake and his wife Jessica Biel might be expecting another bundle of joy.

According to Naughty Gossip on Wednesday, the celebrity couple is keeping quiet about their baby news, but close friends say that the actress might already be three months pregnant with the couple's second child. They already have one son, Silas Randall Timberlake, who was just born last August.

One source said that Timberlake and Biel are keeping their baby news "quiet," as they didn't expect to get pregnant so fast after their first baby was born.

One insider told the site, "If they are pregnant they are telling no one. It is no secret that they have been trying to have more kids. They love being parents an have the money and resources to have a huge family. Justin is the best dad ever, but they try very hard to keep their private live, private!"

In fact, Timberlake and Biel have been managing to keep little Silas out of the spotlight and are rarely seen in public with the 7-month-old tot. They have, however, shared photos of the boy on their social media accounts.

So far, a rep for the couple has not made any comments about the pregnancy rumors.
