Justin Timberlake and Jessica Biel to have 'a big wedding'

Wellington, Mar 26(ANI): Jessica Biel and Justin Timberlake are reportedly planning a huge wedding when they get married in August.

The two have an abundance of loved ones they will ask to witness their union.

"It will be a big wedding...They have lots of people they want to invite," Stuff.co.nz quoted a source as telling Us Weekly magazine.

The actress's future mother-in-law Lynn Harless has selflessly assisted her throughout the planning.

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

Beil is now said to be narrowing down her favourite designs to choose the perfect wedding dress.

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

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.

The couple so far kept details of their relationship private, with Biel only showing off her engagement ring for the first time in February. (ANI)
