The insider claims that Jen and Vince have yet to set a date, but that Jen said she’d like the wedding to happen “sooner rather than later." The proposal, Aniston confessed to Mrs. Pitt, took place while she and Vaughn were in Paris promoting The Break-Up. Vince allegedly presented Jennifer with a 9.5 carat canary diamond ring.

Though a date has not been set, Vaughn and Aniston have already set about planning their wedding. Jennifer doesn’t want to make as big of a fuss on the second time around, having spent $1 million on her first wedding to Brad Pitt. This time her ceremony will probably be a low-key event in Chicago. "There will be more of Vince's Chicago friends than Jen's Hollywood crowd," says a source. Still Jen will have at least one Hollywood pal by her side – she’s asked Courteney Cox to be her matron of honor. Cox’s daughter Coco will serve as a flower girl.

Don’t expect Vince and Jen to announce their engagement any time soon. The couple is hesitant to share their good news because they don’t want to steal the spotlight from Brad and his girlfriend Angelina Jolie. Says a source close to the couple, “This is Brad and Angelina's moment. It'd be tacky for Jen and Vince to announce the engagement so soon after Shiloh's birth." A friend of Jennifer’s claims the actress said, "I'll share it with everyone when I want to."
