It looks like Justin Timerberlake and Jessica Biel may be undergoing marital woes, according to Timberlake's grandmother Sadie Bomar.

The 31-year-old actress and 33-year-old performer have been married for almost a year-and-a half now, but apparently their relationship is very worrisome to Timberlake's grandmother, who opened up about her concerns two years after spilling the beans about her grandson's engagement to Biel.

"They are married, but they are so busy, both of them, it's hard going," Timberlake's grandmother told the Mirror.

She continued, saying that their busy schedules are making it hard for the them to consider starting a family. "I'm sure when it's right to have children they will, but not now."

She added that although the couple loves each other, she is worried that their distance will hurt their relationship. "They do love each other dearly, but they are apart so much it's going to be hard going for them," she said. "I think Jessica finds that really tough. She's on her own a good deal."

Because the couple spends so much time apart, it has fueled rumors that they are having marital issues, however, Hollywood Daily News reports that Timberlake's mom, Lynn Harles, recently addressed these rumors on Facebook, posting:

"I really try not to comment on bulls-t stuff, but I get so sick of all these stupid tabloids printing all the crap that they do about my son and his beautiful wife, who by the way are immensely happy and so much in love! Why don't some of you act like journalist [sic] and print a real story! Report some actual news and stop making up rumors about people's lives who are otherwise VERY happy!"
