Jennifer Aniston and Vince Vaughn engaged and to wed this summer?

Grazia magazine is reporting that Vince Vaughn has proposed to Jennifer Aniston.

According to the magazine’s source, Vince did the deed on a recent trip to Las Vegas, presenting Jennifer with a £100,000 engagement ring.

“They haven’t set an exact date yet, but are talking about early summer,” the source revealed. “Both Jen and Vince are clearing their schedules to have some time off to spend together on a proper honeymoon.”

The Sunday Express reported at the weekend that Oprah Winfrey is apparently going to be hostess for the event, with her lavish estate in California set to be the location for the nupitals.

According to their source, Jennifer “wants this to be grand and lavish on a scale not witnessed since Liz Taylor’s marrying heyday.”

“Jen is more convinced than ever that Vince is the one.”
