Jessica Biel Reportedly Wants Her Son To Have 'Good Values'

On Friday, E! News posted details from Nsync member Lance Bass when he spoke to talk show host Meredith Vera. He mentioned that Timberlake has indeed changed since his wife, Jessica Biel, gave birth to their son, Silas, last April.

"It's been five months and it's so amazing to see a friend go through this because you know, I grew up with him since he was 14-years-old," Bass said about Timberlake. "But to see this amazing dad now...all he wants to talk about is the kid."

Bass then added that he would like to have kids of his own someday.

"[Justin's] completely changed and you have to," he said. "I mean I can't wait to be a dad myself just because I would love to know what the selflessness feels like."

Bass explained that he and his husband, Michael Turchin, want to become fathers hopefully in two or three years.

"I know people are very on the fence with the IVF and all this stuff, but people have been doing it for years," the former Nsync member said. "With us, of course we want to find a surrogate to have our own kids, but now I was just reading with stem cell research and all this, and that's of course up to the minute, now they are saying with the skin cells of a male you can actually produce an egg and fertilize [it], so you can have biological kids with two males."
