Jennifer Aniston is reportedly planning to marry her lover Vince Vaughn on chat show queen Oprah Winfrey's palatial California estate this summer (06). Although she is said to be keen to "upstage" her ex-husband Brad Pitt and Angelina Jolie with a huge bash, the former Friends actress wants to wed her The Break Up co-star for all the right reasons. A pal tells British newspaper the Sunday Express, "She wants this to be grand and lavish on a scale not witnessed since Liz Taylor's marrying heyday. "Does she want to upstage Brad and his bride-to-be Angelina? You bet! Jen's wedding is going to be the talk of Hollywood. "Jen is more convinced than ever that Vince is the one."
