Olivia Newton-John apparently can't get enough summer lovin'.

The Grease star has swapped vows with beau John Easterling twice in the past month, according to People.

The couple finally announced their marital status July 4 to a bunch of surprised guests, who had arrived at the couple's Malibu home for an Independence Day barbecue not knowing that the 59-year-old Grease star and the 56-year-old American businessman had made things official.

The newlyweds, who had been dating for about a year, first did the deed in Cusco, Peru, on June 21. They then followed up with a June 30 civil ceremony in Jupiter, Fla. The latter was officiated by a friend of the entertainer and attended by just the bride and groom, who's the CEO of Amazon Herb, a company that sells aromatic plants from the rain forest, per Entertainment Tonight.

The Grammy-winning "Physical" singer and Amazon John were each married once before.

The British-born, Australia-reared Newton-John was previously hopelessly devoted to Matt Lattanzi, at least until 1995, when they divorced after he had an affair. She and Lattanzi had a daughter, Chloe, now 22.

She subsequently began dating Patrick McDermott, but he later vanished from a  chartered fishing boat off the California coast in 2005.
