Justin Timberlake with his 'NSYNC bandmates

Justin Timberlake's former 'NSYNC bandmate thinks he's going to be "a great dad."

Joey Fatone says the 'Not a Bad Thing' hitmaker, whose wife Jessica Biel is reportedly pregnant, will be a "very hands-on" father.

He said: "I think he's going to be a great dad."

The 37-year-old singer says Justin, 33, looked after his younger stepbrother, Steven, when they were growing up and "took him under his wing."

He also told PEOPLE.com: "He's always been great with kids in general. He's going to be great. I think he'll be very hands-on."

Joey predicts Justin will "start slowing down" when he completes his '20/20 Experience World Tour' in January.

He added: "He'll be taking some time off for sure."

The 'SexyBack' hitmaker and 'Total Recall' star Jessica, 32, have yet to comment on rumours she is expecting their first child, but the brunette beauty, who is gearing up to open her first organic children's restaurant, Au Fudge, in Los Angeles, has been hiding her figure under loose clothing in recent weeks.

A source close to the couple previously claimed they are "worried" about confirming their baby news.

The insider said: "They've been trying for a while to get pregnant, there've been some issues so that's probably part of it too, they don't want to announce it until it's further along and they're out of the woods for a miscarriage."
