Justin Timberlake Bonded with Tiger Woods Over Parenting While Famous

Not many people know what it's like to balance parenthood with global mega-fame -- but Tiger Woods and Justin Timberlake do ... and JT says it's brought them closer together.

In fact, Timberlake just wrote about his friendship with Tiger for Time Magazine -- explaining how the two got to spend some time together last year and really bonded by "talking about being fathers."

Tiger has two kids -- 10 and 11 -- and JT has a 4-year-old son.

"We bonded over the fact that we wanted our children to watch us at our best," Timberlake wrote ... noting that his 4-year-old has just "started to realize what I do."

The coolest part of Justin's story -- Timberlake says in 2018 Tiger told him one of his biggest life goals was to win a major in front of his kids.

Fast forward to April 14 in Augusta ... Tiger wins The Masters and his kids are RIGHT THERE to give him a big 'ol hug.

Timberlake says he couldn't have been happier for his friend -- "What a dream come true."

"All the work he did when people weren't watching allowed him to hug his children on that same hallowed ground he hugged his father 22 years ago, amid all the adulation, a Masters champion once again."

Justin and Tiger have known each other for years and have golfed together a bunch of times.

Tiger has gone on the record praising JT's golf game -- saying the guy has a "beautiful swing" ... but needs to work on his short game if he REALLY wants to get to the next level.
