Justin Timberlake puts a ring on it, reveals Grandma

He hasn't said anything yet and neither has his intended. But Justin Timberlake's grandmother is more than happy to share his wonderful news with Jessica Biel.

Sadie Bomar apparently told a US website: "He called me on Christmas Day and told me he's engaged," adding that her superstar grandson asked her not to reveal the secret "until after the holidays".



She says: "The family loves Jessie … she's a very sweet girl."

The proposal apparently came when the couple were on a holiday to Montana when Justin presented his sweet girl with a custom-designed ring. 

Their five-year romance went through a rocky patch last year when they spent several months apart – supposedly because The Social Network actor was reluctant to commit.

It was clear, though, that Justin still felt deeply about her because shortly afterwards he told Vanity Fair: "She is the single-handedly most significant person in my life. In my 30 years, she is the most special person, okay? ...

"I don't want to say much more, because I have to protect things that are dear to me – for instance, her."
