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."
