How Justin Timberlake and Jessica Biel Are Navigating ‘New Normal’
 
														
Jessica Biel has been by husband Justin Timberlake’s side amid his battle with Lyme disease.
“Jessica has been extremely supportive of Justin’s health and wellness,” an insider revealed exclusively in the latest issue of Us Weekly, on newsstands now. “They’re both strong people, and they’re great at finding a good balance for both of their needs.”
Timberlake, 44, revealed his “relentlessly debilitating” diagnoses via Instagram on July 31, opening up about the “massive amount of nerve pain,” fatigue and sickness he’d been feeling behind the scenes of his Forget Tomorrow World Tour, which concluded on July 30.
“Among other things, I’ve been battling some health issues, and was diagnosed with Lyme disease — which I don’t say so you feel bad for me — but to shed some light on what I’ve been up against behind the scenes,” the “Mirrors” singer wrote. “I was faced with a personal decision. Stop touring? Or, keep going and figure it out. I decided the joy that performing brings me far outweighs the fleeting stress my body was feeling. I’m so glad I kept going.”
He continued: “Not only did I prove my mental tenacity to myself but I now have so many special moments with all of you that I will never forget. I was reluctant to talk about this because I was always raised to keep something like this to yourself. But I am trying to be more transparent about my struggles so that they aren’t misinterpreted.”

Despite balancing several of her own acting and business endeavors, Biel, 43, has been a beacon of support for the Grammy winner and their sons, Silas, 10, and Phineas, 5, who are her “first priority,” according to the insider.
“She’s been incredibly emotionally supportive when he needs her,” the insider said. “They’re navigating Justin’s new normal very well. … The family cherishes their time with each other more than ever.”
Moreover, their extended family has been pitching in to support and spread positivity.
“They have so much support around them too [from] both Justin and Jessica’s family,” said the source. “He has so much love around him and everyone’s just praying for his healing, for a full recovery.”
Following the tour, which kicked off in April 2024 and included a total of 121 shows, Timberlake has been focused on rest and his businesses, taking time to write and play music at home as well, which has been “very relaxing and therapeutic for him,” the insider says.
The singer shared his own gratitude for his wife and sons’ support in his Instagram statement, writing, “Nothing is more powerful than your unconditional love. You are my heart and my home. I’m on my way…”

Canes Set for Showdown Against Rival Gators
 
														
Beck, of course, isn’t the only Hurricane eager to get on the field and face the Gators (1-2).
Defensive lineman Rueben Bain Jr. is a Miami native with deep ties to the Hurricanes program.
Last August, he took the field at Ben Hill Griffin Stadium when Miami traveled to Gainesville for its season opener against the Gators. But Bain was hurt on the game’s opening drive and unfortunately, wasn’t able to provide much more than encouragement and support to his teammates during Miami’s 41-17 win.
Now healthy, Bain has emerged as one of the leaders on Miami’s defense. He has a team-high 15 tackles, 2.5 tackles for loss, 1.5 sacks, an interception and a forced fumble.
And like the rest of his Miami teammates, he’s eager for the latest installment of the Miami-Florida rivalry.
“It was very frustrating,” Bain said, of getting hurt and having to miss the bulk of last season’s game against the Gators. “But last year was last year. We’re just focused on this year and I’m super excited for the chance to just go out there and play football again. Very healthy, just play the brand of football that I want to play. It’s an amazing opportunity. I get to just do something again for another week.”
The Hurricanes know that while there’s plenty of excitement for Saturday’s game – both ESPN College GameDay and ACC Huddle will be featuring the rivalry showdown – their opponent poses a unique challenge.
Florida is coming into the game after back-to-back losses to USF and LSU. The Gators have dropped out of the national rankings and quarterback DJ Lagway had one of the worst outings of his career throwing five interceptions against the Tigers last week in Baton Rouge.
But Miami’s players and coaches know the kind of talent Florida has on its roster and they understand full well the Gators would love nothing more than to come to Hard Rock Stadium and upset the Hurricanes in an effort to get their season righted.
“The part that has to be respected most is their talent level, their coaching, their size, speed, physicality,” Miami head coach Mario Cristobal said. “Schematically, they’re very challenging in a lot of different ways. They were playing elite defense for several games, [going] back to last season and offensively, they’ve been very close on several occasions to having some great performances. It’s very clear they’re an extremely talented team, they’re well coached, they play hard, and for us, it’s a great opportunity.”
Added Hurricanes running back Mark Fletcher Jr., “Last year, it was fun doing that. It was fun. But I’m pretty sure those guys, they’re coming here to play football. That’s a very well-coached team. Those guys fly around. [They’re] extremely talented on both sides of the football. So, we just have to be on our A game and we’re ready for the challenge.”
