Natasha Richardson's son is reflecting on her legacy.
While marking the 15th anniversary of the Parent Trap actress' death, her youngest son with husband Liam Neeson, Daniel Neeson, shared a heartfelt tribute.
"15 years since you've left this plane onto forever more," the 27-year-old wrote on Instagram March 18 alongside a black and white portrait of his mother. "I look forward to re uniting one day but for now I take solace in knowing you're beside me every step of the way."
Daniel and his brother Micheál Richardson were just 12 and 13-years-old, respectively, in 2009 when Natasha died at the age of 45 after suffering a head injury while skiing.
Calling his mom "the OG margarita mama," Daniel explained how he continues that legacy, including with his own liquor company, DE-NADA Tequila. He also thanked his aunt, actress Joely Richardson, for reminding him that "we're on an ever spinning planet."
"Change is inevitable and we must embrace it with open arms," he added. "We're all interconnected here and over there through love. The greatest life force. choose it above all else."
Andy Cohen, a longtime friend of Natasha's, commented on Daniel's post, writing, "Love you so much Danny. And so proud of you. Your mom would LOVE your margaritas, and she was the supreme connoisseur!"
The Watch What Happens Live host also shared a separate tribute where he noted how "perfectly marvelous" Natasha "left a profound impact on her friends, and on millions who she touched as an artist."
"We were a merry bunch bound completely together by Her," he continued. "If you can, raise a glass today to the great Natasha Richardson and let her know we all miss her down here."
In the years since her passing, both Liam—whom she wed in 1994—and their boys have reflected on their grief. Micheál even changed his last name to Richardson in 2018 to honor Natasha.
"I think the pain was a little too overwhelming," he told Vanity Fair in 2020. "I think the mind is very powerful, and subconsciously, or unconsciously, it can protect you. That's what it did when she passed. I just pushed it aside and didn't want to deal with it."
