Jessica Biel Doesn't Trust Herself With Justin Timberlake's New Album Yet: 'I Have a Big Mouth!' (Exclusive)

The adorable couple revealed whether Biel appears on 'Man of the Woods' and Super Bowl plans.

Justin Timberlake and Jessica Biel are kicking off a big year in style.

The adorable couple made it date night at the Golden Globe Awards on Sunday, where Biel is a first-time nominee in the star-studded Best Actress in a Limited Series or TV Movie category for her powerful performance in USA Network’s The Sinner. The 35-year-old actress was grateful to be a part of such a big night for women, referencing the Time’s Up movement.

“Honestly, it’s the most spectacular thing,” Biel told ET’s Nancy O’Dell on the red carpet. “Just to be next to these other nominees in this category -- first of all, you say, ‘I’ve never been nominated before, so that in itself is just the biggest honor,’ and then have it be a year like this where we are searching for equality and looking to empower women. It feels so solidifying as women and as humans because it’s not just a woman’s movement tonight. This is a human movement that we are all doing together. It just feels extra special and honestly, [it] doesn’t even matter what happens. I feel like I’ve won just standing here already, so I can relax.”

Timberlake revealed that when news of Biel's nomination came through in December, he couldn't contain his excitement.

“I was the worst example for my son [Silas]. I actually started jumping on the bed, so I had to have the whole day of ‘No, son, don’t do what I'm doing. Do as I say,’” gushed Timberlake, wearing a Time's Up pin. “I'm so proud of her. I saw how much she put into it and how hard she worked. She would come home every day exhausted from how emotionally taxing this role was for her and also as a producer. She really, I guess for lack of a better term, took the bull by the reins and said, ‘I'm gonna do this project,’ and did it.”

It’s been a momentous several days for Timberlake. Just last Friday, the 36-year-old released his first single, the dance/funk-inspired “Filthy,” off his anticipated fourth studio album, Man of the Woods, which hits shelves Feb. 2. In the album version of the track, many have speculated that the female voice in the last 20 seconds may indeed be Biel.

“It may or may not be my wife,” Timberlake coyly said, when asked to confirm if the rumors were true. “Probably a little bit, maybe she is…”

Biel chimed in, adorably revealing that she was going to stay out of the speculation for fear of “getting in trouble.” “I have a big mouth!” she admitted. “I don’t get to have any of the songs. I have none of the album. Just in case something happens, I don’t want to be the one responsible for it getting leaked on my phone.”

As for what Timberlake’s Super Bowl halftime show on Feb. 4 will entail, the singer said they’re just getting into the nitty gritty of it now that the holidays are over.

“I'm getting there,” he said of the planning process. “We're just coming back from the holidays, so we really took the break and enjoyed it with our family. As soon as we get through tonight, I think I'll buckle down and start really zoning in on what we're going to do.”

Whatever Timberlake has planned, Biel already knows her hubby will kill it on TV’s biggest stage: “You're just a little bit undeniable, babe.” “We try. Wow, I feel like I'm winning tonight!” Timberlake adorably replied.

As long as the dancing robot in JT’s “Filthy” music video is at the Super Bowl halftime show, we’re totally in.

The 75th Golden Globe Awards, hosted by Seth Meyers, airs live coast-to-coast on Sunday at 5 p.m. PT/8 p.m. ET on NBC.
