It appears Jessica Biel and Justin Timberlake’s marriage is still on shaky ground.

According to a report from the most recent U.S. print edition of OK! magazine, the "I Now Pronounce You Chuck & Larry" actress has freed her work schedule in an effort to accompany Timberlake on his upcoming world tour due to fears that he may cheat while on the road. “Being apart from your spouse for weeks or months at a time isn’t healthy in Jessica’s eyes. She fears she and Justin will grow apart,” an unidentified friend told the magazine, adding that groupies have also given the 31-year-old film star a cause for concern.

“Jessica is well aware that women throw themselves at Justin when he’s on tour,” said the insider, adding, “There is temptation there and that makes her very uncomfortable.”

While Biel may be ready to join Timberlake on his "The 20/20 Experience" world tour, the 33-year-old “Suit & Tie” singer is reportedly less than thrilled about her plans. “Justin was in shock when Jessica surprised him with the news,” said a source, adding that despite the performer’s love for his wife of two years, he isn't a fan of her surprise. “Justin is going to make the best of having Jessica with him on this tour but he isn’t excited about it,” the insider revealed.

Despite OK! Magazine’s reports, Gossip Cop confirmed that Biel has been known to accompany Timberlake on the road before. “[Jessica] also has a life and work and cannot be everywhere,” a source told the gossip site Wednesday, going on to call OK!’s claims the “most ridiculous thing.”

This isn’t the first time the duo has been accused of having martial issues. Back in January, OK! Magazine published reports that the pair were feuding over Timberlake’s busy touring schedule, a difference of opinion over when to start a family, and Timberlake’s alleged liaisons with other women. According to the gossip site CelebDirtyLaundry.com, the couple were living separately earlier this year and considering a permanent split.

Timberlake last dispelled rumors regarding their divorce at the 2014 People’s Choice Awards last month by thanking Biel during his acceptance speech while receiving the award for “Favorite Male Artist.” “I would like to thank my beautiful wife for teaching me patience,” said the singer, who also gave martial advice to TV viewers. “Just putting the dishes in the dishwasher, it goes a long way. Fellas, you’re welcome.”
