Justin Timberlake and Jessica Biel were at the center of marriage trouble rumors, but those split rumors have been debunked now that photos have surfaced of their romantic getaway vacation for Jessica Biel's 32nd birthday!

Justin Timberlake's grandmother, Sadie Bomar, told the Sun recently that she was worried about Justin Timberlake and Jessica Biel's marriage, suggesting that the couple rarely saw each other because the "Mirrors" singer is away on his "20/20 Experience World Tour."

But now her fears can be put to rest because Justin Timberlake and his wife were spotted in Barbados celebrating Jessica Biel's birthday, which fell on March 3. Though it was eleven days after Biel turned 32, the vacation seemed to make up for it!

According to the Boston Herald via Us Weekly, Justin, 33, and his wife checked into a private villa near the top-of-the-line Sandy Lane resort. Timberlake then chartered the $1,125-per-day catamaran Seaduced for wakeboarding on March 14.

"They looked madly in love as they joked around," a witness said.

"Justin wasn't very good at wakeboarding," an onlooker told Us Weekly. "Jessica was much better!"

As we previously reported, rumors that Justin and Jessica's marriage was in trouble began when they hadn't been seen in public for a while, and then Biel didn't join Timberlake for the 2013 American Music Awards on Nov. 24. She also skipped the 2014 People's Choice Awards.

Biel recently revealed to The Daily Beast how she stays close to her husband, despite his hectic schedule as a music icon:

"It's not easy... Your relationship just has to be a priority, you have to make sacrifices for it, and you have to make time to see each other no matter what. You have to pick whatever number of days as your cut-off point, and no matter what, one person has to make the journey to see the other person if one of you is far away. It has to be important enough to you to make the effort, because it is a lot of effort," she said.

Timberlake and Biel married in October 2012.
