Actress Lizzy Caplan wed British producer Tom Riley in Italy over the weekend (02-03Sep17).

The Mean Girls star tied the knot in the town of Ravello on the Amalfi Coast in a romantic ceremony attended by several high profile stars.

According to Us Weekly, the 35-year-old's Bachelorette co-star James Marsden was among the guests, along with Tom Hiddleston, Octavia Spencer, Chris Hemsworth, Lilly Collins, and her Now You See Me 2 castmate Dave Franco.

"Lizzy and Tom wanted a destination wedding, and Italy is one of their favorite places," a source tells the publication.

Stylist Ilaria Urbinati posted details about the event via Instagram on Sunday (03Sept17).

"Thank you Ravello and the amazing group of friends this weekend - I hadn't laughed that hard, eaten so well, stayed up so late, danced, and drank so much wine in way too long," Urbinati wrote. "And got to witness so much love between two people that I also hadn't been moved to quite so many tears in a while."

On Monday (04Sept17), Riley took to the photo sharing site to post a sweet photo of himself sitting in the grass next to his new bride.

"This one seems fertile. She shall make a satisfactory first wife," he jokingly captioned the image.

Earlier this year, Riley shared a loving birthday message to Caplan and expressed his excitement for their upcoming nuptials.

"Happy Birthday to my forever mancrush Monday," he wrote alongside a photo of the couple. "A girl whose fake laugh game humbles and inspires me. She was truly miserable in this picture but you would NEVER KNOW and it’s that kind of ability to suppress emotion that will serve us well in our life together.

Caplan and Riley, 36 met in January, 2015, while the Masters of Sex beauty was working on a film in London. The pair became engaged in May, 2016.
