Rumor has it, Jessica Biel and Justin Timberlake are in the middle of planning a big summer wedding.

“Justin and Jessica are planning a big (summer) wedding,” a source told PEOPLE. “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.”

On the wedding, a source claims, “Justin has promised her the best day ever.”

Justin, 31, and Biel, 30, got engaged over the holidays while vacationing in Montana.

Here are some new pictures of Jessica Biel leaving the Elie Saab and Giambattista Valli boutique in Paris, France. Sources claim she’s shopping for wedding dresses!

PS: Check out her engagement ring! Apparently Justin custom-designed the six-carat ring himself.

“Jessica’s stylist really wanted Justin to come to her when picking out and designing the ring,” a source told US Weekly.

“She obviously knows what looks best on Jessica, and what type of things she likes to wear. They talked about it in advance and then Justin completely went rogue without telling Jessica’s stylist, and decided to design the ring on his own,” the source said.

The source was quick to note that this doesn’t mean Biel isn’t a fan of the bauble her fiance chose.

“But I wouldn’t necessarily say it fits her style,” the source added.

I’d say not many girls would turn that ring away.

PICS: Fame/Flynet

Audrina has just taken to her blog to address the rumor circulating about LC and Justin Bobby hooking up. Here’s what Audrina has to say, via her website:

“I woke up this morning and it seems like just about every gossip magazine or blog has a story about Lauren hooking up with Justin.

I’m not sure what to believe. Though Justin and I have not been exclusive for quite some time, these rumors are very confusing and hurtful”

And Lauren, in her usual bitchy way – responded:

“These accusations are so crazy it’s difficult for me to take them seriously.While my usual taste in guys isn’t always perfect, I do prefer they shower regularly.”
