Justin Timberlake Shares An Adorable Throwback With His Mom

Justin Timberlake is one proud son!

In honor of Lynn Harless' birthday on Tuesday, Timberlake took to Instagram to share an adorable throwback shot of the mother-son duo. Looks like little Justin and his mom enjoyed some quality time at the beach together back in the day. 

"Happy Bday to my first partner in crime and the FIRST QUEEN OF THE HOUSE," Timberlake captioned the photo.

"We have been through so much together and I love you more than words can begin to describe. Everything I am and continue to strive to be is because of you. I love you, Momma!#UandMeVsAnybody," he finished the heartfelt message. 

The "Mirrors" singer is going to be a parent himself soon! Timberlake's *NSYNC bandmate, Joey Fatone, confirmed to InTouch that Timberlake's wife, Jessica Biel, is pregnant.
