Big wedding for Biel and Timberlake

Justin Timberlake and Jessica Biel "have lots of people they want to invite" to their wedding.

The pair are currently planning a sumptuous commitment ceremony.

Like most couples, Biel and Timberlake have an abundance of loved ones they will ask to witness their nuptials.

"It will be a big wedding," a source told Us Weekly magazine. "They have lots of people they want to invite."

Biel is not too overwhelmed with the event planning, as her future mother-in-law Lynn Harless has selflessly assisted throughout.

"She's helping Jessica with every little thing," the source continued.

However Biel is hands-on about choosing the perfect wedding dress and is now narrowing down her favourite designs.

"Monique Lhuillier has sent over some sketches," a source said. "She's Jessica's first choice."

Biel, 30, and Timberlake, 31, have been together on-and-off for around five years.

Timberlake is understood to have popped the question over the Christmas break while the pair were holidaying together.

They have so far kept details of their relationship private, with Jessica only showing off her engagement ring for the first time in February.
