Justin Timberlake and Jessica Biel's marriage has never been stronger, despite the couple having faced numerous challenges over the years, according to an insider who spoke to a magazine. The couple's unwavering love for each other was on full display during the Vanity Fair Oscars after-party on Sunday, March 10, where they were seen holding hands, taking selfies, and cuddling on the couch throughout the night.

"They looked and acted like two teenagers in love," the source revealed to Life & Style. "Whatever they're doing to keep the romance alive, it's working!" The insider's comments come after the couple has weathered several storms in their relationship, including accusations of infidelity and public scrutiny.

In 2019, photos surfaced of Timberlake, 43, holding hands with his Palmer co-star Alisha Wainwright, leading to speculation that he had been unfaithful to Biel, 42. The singer denied the cheating allegations but admitted to crossing the line in a public apology, stating, "I displayed a strong lapse in judgement. I drank way too much that night and regret my behavior. I should have known better."

Timberlake also apologized to his wife and family for putting them through an "embarrassing situation" and pledged to focus on being the best husband and father he could be.

Two years later, the pop star found himself in the spotlight again after the premiere of the documentary Framing Britney Spears, which highlighted the poor way he spoke about ex-girlfriend Britney Spears following their 2002 split. The documentary also revived conversations around "Nipplegate," referring to the incident during the 2004 Super Bowl halftime show when Timberlake exposed Janet Jackson's chest, leading to her being somewhat blacklisted from Hollywood while his career continued to thrive.

In response to the backlash, Timberlake issued a public apology, stating, "I am deeply sorry for the times in my life where my actions contributed to the problem, where I spoke out of turn, or did not speak up for what was right. I understand that I fell short in these moments and in many others and benefited from a system that condones misogyny and racism. I specifically want to apologize to Britney Spears and Janet Jackson both individually because I care for and respect these women and I know I failed."

The couple faced further scrutiny last year when Spears released her memoir in October, which revealed that Timberlake had cheated on her more than once during their early 2000s romance and had encouraged her to have an abortion when she became pregnant.

While Biel was not directly involved in these incidents, a separate source claimed that the backlash Timberlake faced did take a toll on him. However, the couple's bond remains unbreakable, with Biel continuing to stand by her husband's side.

Looking ahead, the insider acknowledged that Timberlake's upcoming tour will "be hard on them" as a couple, but noted that "Jessica and the boys [sons Silas, 8, and Phineas, 3,] will visit Justin as much as they can."

Despite the challenges they have faced, Timberlake and Biel's marriage appears to be stronger than ever. Their loved-up display at the Vanity Fair Oscars party is a testament to their enduring love and commitment to one another, and their ability to overcome obstacles together.

As the couple prepares for Timberlake's upcoming tour, they will undoubtedly face new challenges, but their unbreakable bond and determination to support each other through thick and thin will likely see them through. With Jessica Biel standing firmly by Justin Timberlake's side, the couple seems poised to continue weathering any storms that come their way and emerge stronger than ever.
