Explosive! “Five rules Adele gave to Rich Paul that make their marriage work.

Songbird Adele, 35, is reportedly ready to get hitched and have a baby with sports agent beau Rich Paul, RadarOnline.com has learned.

The 35-year-old Easy on Me singer is heading to Europe this summer for her first overseas concert since 2016 — and sources spill she’s bringing Rich along for the ride!

In November, the British singer gushed over her American sweetheart at a Los Angeles comedy show — and called him her husband.

Now, an insider tells the National Enquirer, “They’ll nip off to London, see family and friends and throw a small ceremony. At least that’s the plan right now.”

“She’s super excited about showing Rich more of her heritage,” the source added. “It’s been on their to-do list for literally years now.”

“Being in Europe gives her that perfect opportunity and he’s thrilled to be able to go with her.”

Sources squealed the Someone Like You hitmaker — who is mom to 11-year-old Angelo, her son with first husband Simon Konecki — has allegedly been working on baby number two for some time.

“The talk among her inner circle is that she’s hired a surrogate and is planning for a baby this year,” an insider said. “She’s wanted another baby for a long, long time. Now it looks like it’s going to happen very soon!”
