Jessica Biel and Justin Timberlake are still hunting for a perfect wedding location.
The Hollywood couple are set to tie the knot in August but they have yet to find a venue that they like and will be big enough to hold all their guests.
A source told Us Weekly magazine: "It needs to be in California and offer plenty of room! It will be a big wedding. They have lots of people they want to invite."
However, Biel is getting plenty of help from Timberlake's mother, Lynn Harless,who is giving her future daughter-in-law lots of advice on planning the big day.
The source said: "She's helping Jessica with every little thing."
But one thing Biel - who split from Timberlake last year only for them to rekindle their romance before Timberlake popped the question - has decided on is the designer of her dress.
The source revealed: "Monique Lhuillier has sent over some sketches. She's Jessica's first choice."
Despite refusing to confirm their engagement in public, Biel showed off her engagement ring at a party in New York earlier this month, with witnesses guessing it could be vintage.
A source said: "It wasn't huge. It looked vintage and might have been custom made."
