The biggest celebrity love life stories of May 2018

The month of May saw a few weddings, quite a few engagements and some splits in the celebrity world. Wonderwall.com is rounding up the biggest Hollywood love life stories, starting with a whopper — the royal wedding! Prince Harry and Meghan Markle married in a stunning ceremony at St. George's Chapel at Windsor Castle on May 19, and it was watched by an estimated billion people. Meghan donned a gorgeous Givenchy gown and was accompanied by the cutest wedding party we've ever seen for her walk down the aisle: six adorable tiny bridesmaids (including Princess Charlotte) and four page boys (including Prince George). The happy couple said their vows before being whisked away for a ride through the streets of Windsor in a horse-drawn Ascot Landau carriage before heading to a lunchtime reception that included a performance by Elton John. Later that night, they celebrated again at a private evening reception where George Clooney hopped behind the bar. It's safe to say the newly anointed Duke and Duchess of Sussex had the wedding of the year! Now keep reading to get caught up on all the rest of May's romance news…

Becca Kufrin has found love! The week before her series kicked off, the Season 14 star of "The Bachelorette" (seen here with a potential suitor) opened up about her rocky road to romance and announced to People magazine that she's found her "missing puzzle piece." Host Chris Harrison seconded the happy news on Instagram, sharing that an engagement will take place on the show later this summer. As for the man who dumped Becca for runner-up Lauren Burnham, Arie Luyendyk Jr.? Well, he's moving on too: He and Lauren have officially set a wedding date.

The reality stars shared a 44-minute video with People magazine chronicling their romance, which includes swoon-worthy details like the fact that Jared writes her love letters and once filled her apartment with flowers.

Hugh Grant is a married man! The star of many a romantic comedy finally tied the knot himself this month — at the age of 57!

A new (and odd) couple made their debut at this year's Met Gala — SpaceX and Tesla founder Elon Musk, 46, and musician Grimes, 30 — after about a month of dating, Page Six reported.

After Tristan Thompson was outed as a cheater just two days before Khloe Kardashian gave birth to their daughter, True, in April, fans spent weeks wondering if she'd stay with him or kick the NBA player to the curb. They got their answer in early May when the reality TV star and the Cleveland Cavaliers player put on united front: Khloe was photographed by Tristan's side having lunch with friends and at the movies and she even cheered him on during a playoff game at Cleveland's Quicken Loans Arena. "Khloe has stuck with Tristan because she loves him," a source told Page Six. "She has stuck with him over the objections of her mom and her sisters, who begged her to bring the baby back to L.A. and live with the family. They are worried about Khloe — but she insists she's putting their baby first, and she wants to stay a family." A few weeks later, however, Us Weekly reported that things weren't so wonderful. "Khloe and Tristan are fighting constantly. All the time," a source close to Khloe said, adding, "She doesn't know how she's going to rebuild trust in him." On May 27, Khloe took to Twitter to criticize all the people who "love to give advice but are not living the advice that they are offering," she wrote. "Focus on your own world. I'm sure there's cracks there that need your attention. We all got em."

Something tells us we haven't seen the true end of this couple's love story.

Back on again?! The Weeknd and Bella Hadid are always keeping us guessing — and the latest in their are-they-or-aren't-they-together saga happened during the Cannes Film Festival!

Paris Hilton's wedding day is fast approaching! On May 9, the star was spotted meeting with the priest who will be officiating her upcoming nuptials to Chris Zylka.

Back in February, Paris told the New York Post that the wedding would take place in the U.S. but at the time, she hadn't nailed down specifics, sharing, "We're getting so many calls from different hotels and designers and wedding planners and everyone wanting to be part of the big day. We're trying to make the final decision of who the best people are for that."
