Just like they were going to perform and Kim and Kanye's wedding?

The couple - who recently wrapped their US On The Run tour - have been apparently "pencilled in" to play at the nuptials of 50-year-old Brad and 39-year-old Angelina as their kids Maddox, 13, Pax, 10, Zahara, nine, Shiloh, eight, and five-year-old twins Vivienne and Knox are huge fans of the duo. Kinda pricy kiddies entertainment for a wedding. A bouncy castle would be cheaper.

A source told The Daily Star: "Brad told Bey and Jay, that their kids, especially Maddox - adore them. He told them it would make their big day extra special to have them both do a number."

While Beyonce and Jay have said they will try their best to make time to perform at the ceremony they haven't made any promises to appear due to their "hectic schedules".

The source explained: "They were flattered and said they'd do their best to fit it into their hectic schedule, depending on the date." That'd be a no then.

The couple - who have been married for 6 years - sought solace at Gwyneth Paltrow's LA mansion to escape constant speculation about the state of their marriage.

According to reports, the couple are enjoying the privacy that the Brentwood property offers and enjoyed kicking up their heels there before flying to Paris for tonight's gig.
