Rumours regarding Jessica Biel and Justin Timberlake’s engagement first emerged after Christmas when the former NSync singer was said to have proposed.

Since then, little confirmation has been on display to say whether or not the pair intended to tie the knot.

However, last week the couple finally put a sign out to the world that their romance was heading for wedding bells when Biel was snapped alongside Timberlake sporting a sparking diamond ring as they dined out at the Tavern restaurant in California.

The diamond looked to be quite heavy too, which sounds about right in light of the singer’s string of successes that have seen him swap the recording studio for film sets in such movies as the Social Network and Bad Teacher.

Jessica will be welcomed into Timberlakes’ family with open arms if comments by his grandmother are anything to go by.

She recently said: “Jessica is a very sweet girl, she’s upright and everything and we love her.”

Biel, who kicked off her career starring in Christian TV show 7th Heaven, is set to return to cinema screens in The Tall Man later this year.
