“After several breakups and makeups, the third time really is the charm for Meg and John,” spilled a source close to the couple.

“They plan to make things official with a quiet civil service during the Christmas holidays!” Insiders said the affair will probably take place in Meg’s New York apartment and the guest list will be limited to their kids — John’s sons, Hud and Speck, and daughters, Teddi Jo, Michelle and Justice, along with Meg’s children, Jack Quaid and Daisy True Ryan.

The two seemed inseparable recently, according to sources, and have been snapped together multiple times in New York looking attached at the hip!

“They’ve never been closer — and given their history, that’s saying something,” dished an insider.

“They’ve had their problems,” said the source. “But they always KNEW that they’d wind up together!”

Back in 2014, the “Hurts So Good” singer and Meg — who’d dated for nearly four years — split that August after John refused to move to New York City. The Indiana-born rocker then took up with ageless supermodel Christie Brinkley!

Insiders spilled that Ryan's son 25-year-old Jack — whose dad is the actress' first husband, actor Dennis Quaid — couldn’t be happier with the pair’s wedding plans, and has given them his blessing.
