Los Angeles: Singer Justin Timberlake's grandmother Sadie Bomar is worried about his marriage with Jessica Biel.
According to Bomar, the two work really hard and are busy most of the time, reports contactmusic.com.
"They are married but they are so busy, both of them, it's hard going. I'm sure when it's right to have children they will, but not now. They do love each other dearly but they are apart so much it's going to be hard going for them," Bang Showbiz quoted Bomar as saying.
Timberlake exchanged vows with Biel in October 2012.
