Justin Timberlake will never settle down with Jessica Biel — at least that’s the word from JT’s grandma.

The “SexyBack” star is rumoured to have split from the striking actress — with tabloid rumors last week claiming Justin and Jessica are “re-evaluating” their relationship –and now the crooner’s grandmother has revealed that he never had any intention of marrying her.

“Jessica was keen to marry, but Justin isn’t ready. He’s busy writing new material and he works hard to be successful – he’s really focused on that,” Sadie Bomar tattled to Closer Magazine this week. “As far as we’re concerned, he’s always been single. The girlfriends come and go, but we believe nothing has ever been serious. Justin does his own thing and he isn’t ready to marry just yet.”

The couple, who have been dating for around two-and-a-half years, are believed to be going through a rocky patch, but friends denied claims they have already split.
