The triple-threat star participated in the 'Late Show' segment "Big Questions With Even Bigger Stars."

A number of Justin Timberlake's talents were on display when he appeared on Wednesday's Late Show With Stephen Colbert. 

The triple threat star opened up about headlining next year's Super Bowl halftime show, but also proved that he has the singing chops to perform the National Anthem. Upon talking about how both he and Colbert were in church choirs growing up, the two then sang a bit of the "Star-Spangled Banner," and harmonized surprisingly well. 

Timberlake, 36, also jokingly opened up about what it'll be like to be back at the big game after the wardrobe malfunction that occurred in 2004 when he performed with Janet Jackson at the Super Bowl. 

"It’ll be a great show. I'm very excited about it," he insisted, noting that he quickly realized after the backlash of the 2004 Super Bowl halftime show that "a lot of people watch the Super Bowl."

Timberlake also participated in the Late Show segment "Big Questions With Even Bigger Stars" and revealed the inspiration behind his 2006 song, "Sexy Back."

"When you brought the sexy back, where had it gone?" Colbert asked.

Timberlake then quipped that the track was actually about his neighbor's rabbit, Sexy, that he was pet sitting. "They were worried I wouldn't return the rabbit, so I wanted to assure them via song that I was indeed bringing Sexy back," he told the late-night host. "I mean, if you listen closely, it's all in the lyrics."

At the end of the segment, the guys gave a shout-out to Timberlake's pal and Tonight Show host, Jimmy Fallon, exclaiming, "We love you, Jimmy."

Fans are anticipating Timberlake's big performance at the Super Bowl LII, and a source told ET that it's not out of the realm of possibility that Jackson would join him. 

“The door is wide open,” a source close to the 51-year-old singer said. “If Justin or his team did reach out, Janet would perform with him again in a minute.”
