Have you wondered why Paul McCartney has seemed so happy lately? It's because he and Nancy Shevall, his girlfriend of four years, are going to get married! Sources close to the couple say that they "have the right chemistry... they're both cool, chilled out and optimistic." This will be Macca's third trip to the altar. He was married to Linda Eastman from 1969 until her death in 1998, and to Heather Mills from 2002 until their nasty divorce was finalized in 2008.  A Summer wedding is in the works.

The newly-engaged Sir Paul McCartney is hitting the stage in Lima, Peru tonight.  Sir Paul's gig at Estadio Monumental is part of a series of South American dates this month.  Other shows on this leg of the trek include gigs in Santiago, Chile and Rio De Janeiro, Brazil.  Anticipation for the former Beatle's show in Peru is reportedly high.  Fox News reports that as of last Thursday, fans were already lining up at Estadio Monumental for the Monday night show.
