ET has just obtained the marriage license for beloved 'Grease' star Olivia Newton-John and her new husband John Easterling.

Last week, ET broke the news that Olivia married her longtime love in June. The pair had two ceremonies. The first was in Cuzco, Peru on June 21 and the second, a civil ceremony, took place in Jupiter, Florida on June 30th. John's friend performed the civil ceremony, which was only attended by Olivia and John.
