"Over the past year, connection has become more crucial than ever," she wrote on Instagram. "I've been a supporter of @AndieSwim from the beginning as an investor, and now, more than ever, felt like a perfect time to join them in welcoming a summer of freedom and togetherness."

"Especially sharing it with my daughters!" Moore continued. "It was important to me to include my daughters in this campaign, and I hope others seize opportunities in their lives to create meaningful connections and celebrate every moment with the people they love."

Moore previously spent time with her family during the coronavirus pandemic, when she quarantined with ex-husband Bruce Willis and their daughters.

"There's been a lot of challenges and a lot of tragedy with this pandemic, but I also think there's been a lot of gifts and blessings," Moore said during an interview with Naomi Campbell.

"I personally feel like I was really grateful for things slowing down and the time that we had."
