Justin Timberlake, Jessica Biel 'Planning Summer Wedding'

Justin Timberlake and fiancéeJessica Biel are said to be planning a big summer wedding.

Back in January, reports emerged that the formerNSYNC singer had popped the question to Jessica during a pre-Christmas break to Jackson, Wyoming, with the actress showing off her diamond engagement ring last month.

Now, People magazine has revealed details concerning the couple's big day, with a source telling the publication: "Justin and Jessica are planning a big [summer] wedding,

"Jessica initially wanted a smaller, more intimate wedding, but Justin from the beginning wanted a big wedding, and that's what they have decided on."

Apparently Biel has yet to say yes to a dress but the 30-year old is apparently "very involved" in the planning, with Timberlake promising his bride-to-be "the best day ever."

The couple also want to include all their friends in their special day, whenever and wherever that may be.

In 2011, Timberlake opened up a bit about his feelings for Biel to Vanity Fair, telling the mag: "She is the single-handedly most significant person in my life. In my 30 years, she is the most special person, OK?

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

When asked about having to deal with all the attention the pair have received over the years, Jessica told Vogue: "I don't want to talk about it. I don't feel the need to clear anything up.

"It's the most precious thing that I have in my life, and I care about it so much that I don't care about what anyone says or thinks. I have just not addressed it in any real way, and I'm not going to. It's mine. And I really like that about it."
