It happened when a group of about 60 people at Blunt’s 2010 wedding to actor John Krasinski<\/a> took a boat out on Italy’s Lake Como. Streep was there because not only had she worked with Blunt in their fashionable 2006 film, but Krasinski had played her beloved future son-in-law in the 2009 movie It’s Complicated.<\/p>\n “[The DJ on the boat] would sing the songs in half-Italian, half-English,” Blunt told the host of Jimmy Kimmel Live<\/a> when she visited Tuesday to promote her new movie Disclosure Day. “And he started playing ‘Mamma Mia,’ and my mom and John’s mom started ominously dancing towards Meryl.”<\/p>\n Streep starred in the 2008 big-screen version of Mamma Mia!, and, like The Devil Wears Prada, the title proved to be the first of two installments. In 2010, she wouldn’t have yet appeared in Mamma Mia! Here We Go Again, which came in 2018. But she was already known for the film.<\/p>\n The Only Murders in the Building star politely moved with the moms.<\/p>\n “She indulged them,” Blunt told Kimmel, who’d also attended the nuptials. “But I said to her afterwards, I was like, ‘What did you feel when they came for you?’ and she went, ‘I wanted to hurl myself into the lake.'”<\/p>\n Still, Blunt added, “She did it! We have pictures of them all dancing together. It was amazing.”<\/p>\n John Krasinski and Blunt on May 15 Kimmel recalled that many of the people there hadn’t met Streep before, so this was their introduction to the three-time Oscar winner. (Two at the time.)<\/p>\n Oddly enough, the wedding location where Streep’s now famous dancing took place, was actually George Clooney’s estate, and it was also a setting in The Devil Wears Prada 2.<\/p>\n Get your daily dose of entertainment news, celebrity updates, and what to watch with our EW Dispatch newsletter<\/a>.<\/p>\n When Clooney was asked about the property appearing in the trailer for the blockbuster, he seemed unaware.<\/p>\n “Is it really? Oh man, I’ve made it,” he joked to Access Hollywood<\/a> before the movie hit theaters.<\/p>\n More seriously, he added, “The house holds a special place in my heart, because I love going there” and called Blunt a “dear, dear, dear, dear friend.”<\/p>\n Watch Blunt’s full interview with Kimmel above.<\/p>\n![\"John](\"https:\/\/www.newsbeep.com\/ie\/wp-content\/uploads\/2026\/05\/facee10959e21f7a287a342a079e1e10.jpeg\"\/)
