Timberlake's former *NSync bandmate praised Biel after attending the 40th Anniversary American Music Awards nominations at the JW Marriott at L.A. Live in Los Angeles.
Bass told Us Weeky that Biel's tomboyish personality complements Timberlake. "She can get right in there and talk basketball, football and drink a beer with you, and that's what he needs. He needs someone who can hang with the guys."
Of course, Bass, 33, also recognized Biel's obvious surface appeal. "And she has not aged a bit," he added. "My first acting job –- I did 7th Heaven with her –- and I look completely different."
Timberlake is thrilled by the prospect of his upcoming wedding, Bass said.
"I think Justin was ready to marry when he was 14," he said. "He's always been a hopeless romantic and always in love. And he's had amazing, amazing relationships and very long relationships. He's never been one of those that dates a girl here and there... He's a relationship guy."
Timberlake, 31, proposed to Biel, 30, while on holiday vacation in December 2011. Like Bass, he's nothing short of boastful when it comes to his bride-to-be's considerable charms.
"She's a really, really, really special person," Timberlake told reporters during a recent press conference with the Hollywood Foreign Press. "Plus, she's really, really, hot!"
