It’s a total eclipse of the heart.

More than 300 couples are set to tie the knot during a mass wedding ceremony in Russellville, Arkansas on Monday to mark the solar eclipse.

The couples will say “I Do” at an Elope at the Eclipse event just as the moon blots out the sun Monday afternoon.

“It just seems like the coolest wedding that you could ever have,” one bride, Carlotta Cox, told the local 40/29 News outlet.

Cox and her fiancé, Matthew Holloway, who hail from Knoxville, Tennessee, said they have been planning an eclipse wedding for two years.

“Our original destination was Maine. The totality there is like two minutes, and then we were looking for something where the totality was longer, and it was here in Arkansas,” Cox said.

Russellville, which was ranked by NASA as one of the best places in the US to watch the eclipse, is expected to be in the eclipse’s path of totality for roughly four minutes.

Katie Baucom, who is marrying her partner Nicholas Blackwell during the eclipse event, described her upcoming nuptials as a “once in a lifetime type thing.”

“It’s something big. We never really had anything big or major happen to either one of us,” she said.

Meanwhile, one groom, Keegan, told ABC’s “Good Morning America” that it took some convincing to get his partner, Courtney, to agree.

“She was wanting something a little more traditional and, it took a while, but I finally convinced her to get married in the eclipse,” he said.

Organizers say couples have flocked from across the country — including New York — to wed at the Russellville event.

The hundreds of couples will all cut wedding cakes, toast champagne and have their first dance in the wake of the eclipse.

The shadow of the moon will glide across the US, dimming the Sun for millions of Americans living in the solar eclipse’s path of totality, come Monday afternoon.

A couple of hundred million others will bear witness to a partial eclipse.
