Justin Timberlake Has 'Learned From His Mistakes' After Some 'Serious Soul-Searching,' Jessica Biel Is 'Incredibly Proud': Source

Since the start of his career, Justin Timberlake has endured his fair share of scandals. But after welcoming his second son with wife Jessica Biel over the summer and celebrating his milestone 40th birthday on January 31, the superstar is confessing to pals that he feels immense guilt about the past — and he won't be making the same mistakes in the future. 

"Justin's done some serious soul-searching and accepts that he's wronged a lot of people over the years with his own terrible mistakes," a source tells OK!. "He says he's still a work in progress, but step one has been to stand up and admit he's hurt too many women."

In addition to a boozy night out with his Palmer costar Alisha Wainwright in 2019 (Timberlake was photographed holding her hand at a bar in New Orleans) and his part in the now-infamous "Nipplegate" incident with Janet Jackson at the 2004 Super Bowl, Timberlake recently came under fire again due to the documentary Framing Britney Spears, which seemingly showed him exploiting his breakup from the pop princess to help his solo career. 

"Justin's learned from his mistakes and has a lot more sensitivity about the impact of his actions on other people," explains the source. "That's the big difference between the Justin of today and his old, immature self." 

That self-awareness was evident in an emotional statement that the Grammy winner posted to Instagram on February 12, apologizing to both Spears and Jackson for the errors in his ways. His words drew praise from millions of fans — as well as his wife, Biel, 38.

"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," Timberlake said in an Instagram statement.

"She's incredibly proud of Justin," notes the source of his wife. "Jessica says he's come a long way as a husband, a father and, more importantly, as a human being."
