Jessica Biel and Justin Timberlake want two more children.

The 33-year-old actress married the 'Mirrors' hitmaker in 2012 and gave birth to their first child, Silas, in April, but want to add to their brood sooner rather than later.

A source close to the 'Total Recall' beauty said: ''They want to have two more children. And they want their kids to be close in age, so they're working on it.''

Justin, 34, has taken time off to raise Silas over the past few months and his wife is very impressed by his hands-on attitude.

The insider told America's Star magazine: ''It's really proved to Jessica that they can do this.''

The couple spent the first few months of Silas' life at their secluded ranch in Big Sky, Montana, but moved back to Los Angeles over the summer to focus on their upcoming work commitments.

However, they're planning to relocate back to their rural retreat once Jessica becomes pregnant again.

The insider said: ''They think it's the perfect place to raise their family. Justin likes to joke that he's going to grow a beard and become a mountain daddy.''
