Lance Bass thinks Justin Timberlake will be a ''great dad.''

The 34-year-old singer is set to welcome his first child into the world with his wife Jessica Biel in the near future and his former *NSYNC bandmate is convinced they'll be ''wonderful'' parents.

Speaking to PEOPLE.com, Lance, 35, said: ''He's going to be great dad and she's going to be a great mum.

''We all come from the South and knowing Justin's family and how tight they are and they just love each other. It's going to be a wonderful family to have a baby in.''

Justin confirmed earlier this week that he and Jessica, who got married in 2012, are expecting a baby together on Instagram after speculation began to swirl last month when the brunette beauty was spotted enjoying a lunch in Hollywood while sporting a bump.

Alongside a photo of himself caressing the actress' bump, he wrote on his 34th birthday (31.01.15): ''Thank you EVERYONE for the Bday wishes!

''This year, I'm getting the GREATEST GIFT EVER. CAN'T WAIT. #BoyOrGirl #YouNeverKnow #WeDontEvenKnow #WeAreTakingBets (sic).''

Jessica, 32 - who is thought to be around five months along - is said to be ''feeling really good'' and is doing her best to stay fit and healthy throughout her pregnancy.

A source recently said: ''She's in her third trimester now and feeling good. She has stayed active during her pregnancy and tried to get in as much exercise as possible.''
