Justin Timberlake and Jessica Biel Celebrate Her Brother's Wedding in Mexico -- See the Sweet Pic!

Justin Timberlake and Jessica Biel are all about family.
The 37-year-old "Say Something" singer and his stunning wife headed down to Mexico earlier this week to celebrate Biel's brother, Justin Biel's, wedding. The couple was spotted cheering on the bride and groom alongside friends and family during the beach-side celebration.

The Sinner star looked radiant in a beige off-the-shoulder long-sleeve maxi dress. She outfitted the simple gown with pearl earrings and a matching bracelet. Her brown locks were slightly curled, while her beauty look consisted of neutral makeup. 

Meanwhile, Timberlake -- who took a break from hisMan of the Woods tour for the big day -- looked sharp in a black suit with a white button-up and black tie. 

ET caught up with Biel earlier this month, where she opened up about her and JT's plans to expand their family after he said he wants "as many kids as we can." The couple is already parents to a 3-year-old son, Silas.

"Did he say that? Oh, that's interesting," Biel expressed. "You know, kids are amazing. They are really hard, but they are really amazing."
"I think it would be amazing to have a bigger family," she continued. "I don't know if that is in the cards for us, we will see. But I am feeling him. I don't know what that meansexactly, but I like his dedication!"
The actress also revealed how parenting has changed her marriage and how the couple will always have each other's backs.
