Justin Timberlake's grandmother has claimed that he never seriously committed to his relationship with Jessica Biel.

The 'Sexyback' singer, who has been dating Biel for over two years, is rumoured to have dumped the actress for singer Rihanna.

Timberlake's grandmother Sadie Bomar told Closer magazine: "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."

She added: "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."

Despite the rumours, Biel and Timberlake were spotted having dinner at a California restaurant last week, where onlookers said that the pair look "strained".
