Justin Timberlake & Jessica Biel Dish on Their Son’s Latest Milestone

Power couple Jessica Biel and Justin Timberlake were with “Extra's” Mario Lopez on the red carpet at the Emmys, where Jessica was nominated for her work on “The Sinner.”

Justin was beyond proud, gushing, “I can't even put it into words. I watched her do it from scratch. I remember her finishing the book and saying, 'I found my next project,' and watching her will all of it into fruition…To go a whole summer and go so deep into character — I'm her biggest fan."

The pair recently enjoyed a vacation with their son in Italy. Jessica commented, “We love Italy. It's our happy place” Justin added, “If you don't have fun in Italy, there's something wrong with you.”

Of their little guy, Jessica shared, “He's sooo good, sooo big — he started school today, pre- pre-K... it's a big deal… He's just getting so big and so funny. He has beautiful long hair that we haven't cut yet. He's just growing up.”

Justin recently posted a pic of a vintage car on social media, noting, “That was a 1968 Alfa Romeo… I was stuntin' very hard.”

Timberlake said he was able to relate to Mario, who recently suffered a torn Achilles tendon, saying, “I tore my MCL two months ago. It's not as bad as the Achilles. No surgery, just a ton of rehab.”
